4.2.2 Stop Code Acceptor (STPACP)
STPACP is a write-only specific function register (SFR) to be used to change the operating state into the STOP mode
and STOP-D mode. The STPACP returns "0x00" for reading.

How to enter the STOP/STOP-D mode:
Procedure
How to specify the registers
Description
1
Write "0x5n" and "0xAn" (n=arbitrary in 0-F) in
sequence into STPACP register.
Enables to enter the STOP mode or
STOP-D mode only once.
2
Set STP bit or STPD bit of SBYCON register
to"1".
STP=1: Enter the STOP mode
STPD=1: Enter the STOP-D mode
Any other instructions can be executed between the instruction that writes "0x5n" to STPACP and the instruction that
writes "0xAn". However, if write data other than "0xAn" after writing "0x5n", the procedure gets invalid, so need write
"0x5n" again. This stop code acceptor gets canceled by the system reset.
[Note]
Ÿ
Writing to the stop code acceptor is invalid on the condition both interrupt enable bits and interrupt
request bits are "1", it will not get enabled for entering to the STOP mode and STOP-D mode.
