WebbSince we need to use this value in switch_threads, we load it into register edx: .globl thread_stack_ofs mov thread_stack_ofs, %edx. Next, switch.h defines SWITCH_CUR and SWITCH_NEXT as the offset of cur and next within the stack frame (20 and 24; see how this matches with what is shown in the earlier figure). Webb14 aug. 2015 · Those 5 bits controls which pin can drive External Interrupt 1. Here's the register definition from the family reference manual. The desired pin number gets written to the register. For example, if I wanted to map RP1 to External Interrupt 1 (INT1), I would do this: RPINR0 = 0x0100.
