single cycle- all operations (fetcf,decode,execute,writeback..)are performed in a single clock cycle.
Multicycle refers to pipelined datapath where all the above operations are performed in multiple clock cycles.

All of the three options are correct.
Internal register width, determines number of bits a processor is capable of handing at a time. Register width in turn dictates data bus width, and number of bits ALU can process in single go.

There are many Harvard microcontrollers, DSPs are mostly Harvard, but the key advantages of DSP are:
- most instuctions are single cycle, and 16 or 32 bit devices;
- supports special instructions for signal processing: multiplications, multiply and accumulate the result (MAC) in 1 cycle, data adjusting, representation conversion;

As far I know I don't think that you could find a faster way to test the status of a I/O line using a commercial CPU: usually the status of processor's IO line is mapped to a specific bit in one (or more depending on the IO pin count) CPU register. So I suppose that 2 clock cycles are the minimum overhead you could expect to acquire this informatio

The flop to save the CSN could be generated in the same time as the address generation, not at memory level, but at the bus level.
Dependand of the address mapping usage, you could used the MSB bit has direct chip select.
A single bit MSB is used for the CS, and the 16bits-LSB for address.
