Re: MOD5213: Max frequency of GPIO switching speed?

I'm very grateful for your help. I have just one more question:

Is it possible to concatenate these two instructions
moveq #4,%d0
moveb %d0,4010000e

into one instruction:
moveb #4,4010000e?

Re: MOD5213: Max frequency of GPIO switching speed?

Thank you for the answer. It helped me a lot.

For the C code below:
---------------------------------
while(1)
{
sim.gpio.portta = 0x04;
sim.gpio.portta = 0x00;
}
---------------------------------
I got the next assembler code ...

MOD5213: Max frequency of GPIO switching speed?

The system clk frequency of the MOD5213 is 66 MHz. Why is then the frequency of a square wave signal generated on a GPIO pin is just 2.7 MHz. The code I used is:

#include "predef.h"
#include <basictypes.h> // Include for variable types
#include <serialpoll.h> // Use serial polled driver
#include ...
