18. Key-on Wakeup (KWU)
In the TMP86CS49FG, the STOP mode is released by not only P20(INT5/STOP) pin but also four (STOP0 to
STOP3) pins.
When the STOP mode is released by STOP0 to STOP3 pins, the STOP pin needs to be used.
In details, refer to the following section " 18.2 Control ".
18.1 Configuration
Figure 18-1 Key-on Wakeup Circuit
18.2 Control
STOP0 to STOP3 pins can controlled by Key-on Wakeup Control Register (STOPCR). It can be configured as
enable/disable in 1-bit unit. When those pins are used for STOP mode release, configure corresponding I/O pins to
input mode by I/O port register beforehand.
18.3 Function
Stop mode can be entered by setting up the System Control Register (SYSCR1), and can be exited by detecting the
"L" level on STOP0 to STOP3 pins, which are enabled by STOPCR, for releasing STOP mode (Note1).
