Various routines for CM* architectures, altering execution flow.

Function Documentation

arch_delay()

void arch_delay

(

uint32_t

loop_count

)

Provides a small delay.

Parameters

loop_count

is the number of delay loop iterations to perform.

This function provides a means of generating a delay by executing a simple 3 instruction cycle loop a given number of times. It is written in assembly to keep the loop instruction count consistent across tool chains.

Returns

None.
