I am writing a C program to generate Fibonacci numbers until 255 (as 8-bit values) using pic16f887. I try to check the carry bit from STATUS which is ...
I need to write a function that after work sets all registers except r0-r3 to their initial values. I use push and pop, but I can't find which registe ...
I was wondering why the Atmel RISC doesn't have a "clear all" instruction for the status register and only individual flag clear instructors like CLN ...
I'm having trouble understanding how exactly the Status Register (SR) content works. Let's say that the content of (SR) = $0300. How would I figur ...
Is there branchless way to clear 32-bit register depending on status register state? It can be achieved using additional clear register and CMOVcc, bu ...
As I understand, when I'm calling a function, based on GCC Calling Convention, this is what happens: Caller saves values of AX, CX and DX registers. ...
Asked this in class, I think I understand it but not sure so I wanted to confirm. The Status Register has 16 bits, with each bit having a flag. Howev ...
