0: Stop released by INT0 (P4.3) is disable
1: Stop released by INT0 (P4.3) is enable
0: Stop released by any pin of PB is disable
1: Stop released by any pin of PB is enable
0: Stop released by any pin of P4.0 to P4.2 is disable
1: Stop released by any pin of P4.0 to P4.2 is enable
0: Stop released by any pin of PA is disable
1: Stop released by any pin of PA is enable
When stop mode is active, if the stop condition release flag (STPRF) is set before the STOP
instruction is executed, the low level signal on the P4, PA or PB ports will release the stop mode and
a delay of 256 machine cycles occurs right after the stop mode is released, then the next instruction
is executed or the program counter (PC) jumps to interrupt subroutine if the interrupt is enabled and
interrupt request exists.
