Address: 0F008H
Access: W
Access size: 8 bits
Initial value: ⎯ (Undefined)
STPACP is a write-only special function register (SFR) that is used for setting a STOP mode.
When STPACP is read, “00H” is read.
When data is written to STPACP in the order of “5nH”(n: an arbitrary value) and “0AnH”(n: an arbitrary value), the
stop code acceptor is enabled. When the STP bit of the standby control register (SBYCON) is set to “1” in this state,
the mode is changed to the STOP mode. When the STOP mode is set, the STOP code acceptor is disabled.
When another instruction is executed between the instruction that writes “5nH” to STPACP and the instruction that
writes “0AnH”, the stop code acceptor is enabled after “0AnH” is written. However, if data other than “0AnH” is
written to STPACP after “5nH” is written, the “5nH” write processing becomes invalid so that data must be written
again starting from “5nH”.
During a system reset, the stop code acceptor is disabled.
Note:
The STOP code acceptor can not be enabled on the condition of that both any interrupt enable flag and the
corresponding interrupt request flag are “1”(An interrupt request occurrence with resetting MIE flag will have the
condition).
