<Example of STOP mode release>
The device is released from STOP mode in the following condition.
STOP mode release using P3x (STOP2 to 5)
STOP mode release using P20 (STOP)
Key-on Wakeup STOP Mode Control Register
STOPCR
ister (STOPCR).When these pins are used as a release input of STOP mode, beforehand they set to key-on wake-
up by each register of P3 Port. For details, refer to section "I/O Ports".

is because Key-on Wakeup function is comprised of STOP pin and STOP2 to STOP5 pins as shown in the config-
uration diagram.
(0031H)
Note 1: When STOP mode release by an edge on STOP pin, follow one of the two methods described below.
Note 2: When using key-on wakeup (STOP2 to 5 pins) to exit STOP mode, make sure STOP pin is held low and
The P34 to P37 (STOP2 to STOP5) pins can individually be disabled/enabled using Key-on Wakeup Control Reg-
STOP mode can be entered by setting up the System Control Register (SYSCR1), and can be released by detect-
Although P20 pin is shared with INT5 and STOP pin input, use mainly STOP pin to release STOP mode. This

(1) Disable all of STOP2 to STOP5 pin inputs.
(2) Fix STOP2 to 5 pin inputs high or low level.
STOP2 to 5 pin inputs are held high or low level, because STOP mode release signal is created by OR circuit
