Interrupt Priority in timers interrupt dont'work

[gudezi]

I wrote a small code that shows the error
I have two timers at different frequencies and each one at different priority interrupts.
add a couple of whiles to brake each subroutine separately and the inconvenience
is that regardless of the priority of each timer if I leave any of the two processes waiting
both interruptions are stopped I leave you a copy of the code
I would appreciate the help

Code: Select all

#define Led1 RB0_bit
#define Led2 RB1_bit
#define Led3 RB2_bit
#define Led4 RB3_bit

Hi,

Which MCU are you using ? Have you tried running the code through a debugger ?
