I2CEN bit has to be set to turn on I2C module. How are the I2C pins TRISx is set ?
I'm assuming DFT means design for test? What type of DRC errors are you getting? I tend to ignore ones about incomplete tristate buffers if my DFT is just outputting internal signals. I pay more attention to clock crossing. It's more like a set of guidelines. Wes
I can answer initialization for #1 - you start with yourself (the microcontroller) and branch outward 1) Disable all interrupts - some have something akin to a reset command that turns I/O pins off/tristate 2) set the microcontroller itself into whichever mode/configuration is desired 3) setup whatever glue-fpgas or (...)
I don't think the I/O banks consume much power themselves, compared to the core (read the data sheet). You could tristate your outputs, or set them all low, and that might minimize current.
I understand a buffer amplifier followed by an analog switch as an analog tri-state buffer. It's e.g. utilized in sample-and-hold circuits. There are also OP-amps with disable feature. They set the output stage to high Z, but there's a certain leakage current, usually higher than with a true analog switch.
By I2C design, the pin will be only read in open drain state (when it's tri-stated). In other words, it's already set as input.
Hi, I have a doubt regarding resolving the bus contention while doing scan insertion. While I was doing scan insertion using mentor's dftadvisor, I used the command "set test logic -tristate on -bidi on" and then did the scan insertion successfully but at the time of scan tracing using the command "verify scan", I am getting E10 violations. Does t
The 74Hc374 is an octal D type flip flop with tristate output. how the pins of the flipflop would be set if the ic was put in a bus driven system?
Greetings, I am trying to move my two-process FSM to a single process FSM to have a "more modern" style, but code that was working is now crapping out. Will my tristate signal be solid or will it glitch when set up like this? Thanks, Matthew port ( cd : inout std_logic_vector(7 downto 0); . . . architecture . . . signa
Well basic is not my thing so I'm not sure how this works. I cant see where you set the tristate registers to define the ports as inputs or outputs? Also, at the end of the program, shouldn't you have a 'GOTO Start' and a 'Start:' label at the beginning of the program it should loop back to? At the moment, your program ends, the micro will
I'm not familiar with the part that you are using, but generally microcontrollers can set the direction of IO pins. Effectively there is a second register for each pin which sets the pin into tristate. This must be what your textbook is telling you to do. If you do not set the pin to tristate (or input (...)
A “tri state “ bus is directly connected to a set of CMOS input buffers. No other wires or components are attached to the bus wires. Upon observation we can find that under certain conditions, this circuit is consuming considerable power. Why it is so? Is circuit correct? If not, how to correct?
