The location point of interrupt subroutine.

Nest Level Pointer N: used with instruction MC and MCR. MC is master start instruction. When the MC instruction is executed, the instructions between MC and MCR will be executed normally. MC-MCR master control instruction is nested level structure and max. 8 levels can be applicable, which is numbered from N0 to N7.

Pointer P: used with application instructions CJ, CALL, and SRET.

CJ condition jump:

When X0 = ON, program will jump from address 0 to N (designated label P1) and keep on the execution. Instructions between 0 and N will be ignored.

When X0 = OFF, program will execute from 0 and keep on executing the followings. CJ instruction won’t be executed at this time.

CALL subroutine, SRET subroutine END:

When X0 is ON, program will jump to P2 to execute the designated subroutine. When SRET instruction is executed, it returns to address 24 to go on executing.
