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.

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.
