The return address after an interrupt is always the address where the code execution would continue if no interrupt had occurred. For wait

and conditional jump instructions, the address is defined considering the status of the feedback at the moment the interrupt request took

place.

Counter 3 and 4 prescaler register

The counter 3 and 4 of both microcores uses a clock whose period can be programmed to be a multiple of the ck period. Note that the

actual ratio is according to Table 76, Counter prescaler.

Example:

cksys set to 24 MHz (default) with ck_per = 3, resulting with ck at 6.0 MHz

counter_4_per_uc1 = 0001b -> prescaler of 3

counter4_freq = ck /counter_Y_per_ucx = 6.0 MHz /3 = 2.0 MHz
