Implement the following subroutine in PIC24 assembly language. Use the policy established in Chapter 10 6 of the textbook for using working registers for subroutine parameters and locals. // this subroutine implements an uint16_t swap. void u16_swap ( uint16_t* pu16_x, uint 8_t u 8_i,uint8_t u 8_j ) \{ uint16_t u16_k; u16_k = pu16_x [u8_i]; pu16_x[u8_i ]= pu16_x[ 18_j]; pu16_x[u8_j] =u16_k; \}
