Question

Implement the following subroutine in PIC24 assembly language. Use the policy estab- lished in this chapter for using working registers for subroutine parameters and loca II this subroutine implements an uint16 t swap. void u16-swap(uint16-t* pul 6-х, uint8-t u8-1, uint8-t u8.j)( ls uint16-t u16_k; u16-k = pu16-XLu8-1);

please show work and explain steps

Answer 1

void i16vec_add (int16t* pi16_a, int16_t* pi16_b, uint8_t u8_cnt) {

while (u8_cnt != 0) {

*pi16_a = *pi16_a + *pi16_b;

pi16_a++; pi16_b++;

u8_cnt--;

}

}
