sounds like you are interpreting the register values as binary instead of BCD. Exactly. In addition, please review what's told in the RTC-8564 application manual about masking out unused bits.
I checked the LRM but didn't find anything that was specifically SV about bit masking? bit masking is usually just some and operation with a mask to remove some bits from consideration e.g. parameter mask 8'hF0; assign decode_c = (addr & mask) == 8'hC0; In this example we are looking for the addresses that fall between 0xC0 - 0xCF
Although the use of instructions that performs bit mapped access to ports is available to PIC core, in order to provide some code portability to other cores, I usually prefer to do that using bit masking, so that could migrate the program with minimal changes.
105428 Microcontroller: MSP430 ( ) I'M NEW TO MICROCONTROLLER AND STUCK ON THIS PROBLEM FOR AWHILE. Along the way, i know how to bit masking using OR/AND operation. But i have no idea how to convert 12 bit ADC to 9 bit ADC through masking ( as the questions asked) and how masking h
hiii all, How to do via masking in altium designer???
Whether you have subnet masking.?
From a good loudspeaker, white noise sounds very shrill because it is mostly high audio frequencies. Pink noise sounds more pleasing because the high frequencies are reduced by 3dB per octave, something like interstation noise heard on an FM radio (where de-emphasis cuts the high frequencies). When I worked with a few office sound masking systems,
The use of masking can be in a scenario where you have connected two or more devices onto a single port. As you asked about the LCD case, why mask 4 bits and doesn't it work without masking..? The answer is it will depend on the connections. We use 4-bit mode to reduce the no. of pins used, and then if you connect some other device to the remainin
PORTB = 0b11111110; // assigning a value to PORTB unconditionally PORTB &=0b11111110; // reading PORTB and masking OUT the LSB bit ONLY PORTB = PORTB & 0xFE; // same statement written differently PORTB &= (1<
hello everyone 1.Why do we mask the silicon wafer and distinguish the chip into exposed layer and unexposed layer? 2.what is photolithography? (It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate) couldnt understand this line. thank you
Understanding of masking and i am not use WinAVR.
Hello, what is the issue - in my GLS run I see many timing violations, now on selected port/module I wanted to disbale/mask any setup/hold/recovery/removal violation. Question is how do I do that? what command I use? and how I use that command? In VCS I have checked related site, and internet, I came across notimingcheck. But is this c
Looks like a round robin arbiter. Why don't you run the testbench and look at the simulation waveforms. It will become clear what it's doing, which is priority encoding the requests and masking off the most recently serviced grant, then going on to the next request etc. rinse and repeat.
most of the times we need to work with specified bits of registers . most of the times I see in examples the use of masking its an unreadable way . now see the form below: masking for setting GPIO2.1 as output LPC_GPIO2->FIODIR |= 0x2; equivalent of the form above with structures #include "myGPIO.h" GPIO2->DIR1 = 1;
1. Don't start multiple therads on the same topic. 2. The necessity of masking out some RTC register bits (e.g. seconds.bit7) becomes obvious if you read the datasheet.
The port registers P0 to P2 are already defined in reg51.h and you can access it in C expressions. This should answer your question about nibble access, simply think about C shift and bit masking operations. For an optimal implementation you may want to utilize the SWAP A assembly instruction, no idea if the compiler can infer it on it's own.
#1. SCAN Chain is a Serail Shift register structure...where in you can pump in/out data from Chip pins, and with scan_enable control you can bring the data into FLOP from D path instaed for SI path, i.e. known as Capture cycle #2. Compression s is nothing but comressing the data pumped into/out of many registers and masking is if we see any X on
How create green masking to the pcb? can anyone give me some information...
I'm not aware of bit fields supported outside of structures. masking the bits of interest is the usual way, if you intend to suppress unwanted bits.
whether the number gsm can be replaced by the sender's name when making outgoing calls .....? example: if my phone to a friend, then the number who received the form of the name of a friend (my numbers are not stored previously used by my friend) if you can, how the numbers are masking?
