Function
The TMP93CS20 has eight key-on wakeup pins.
A key input interrupt (INTKEY) is generated at the falling edge of a key-on wakeup pin.
A key input interrupt can return from each standby mode and execute an interrupt process.
The key-on wakeup control register (KEYCR) controls the key-on wakeup pins each 1 bit.
Note: The key-on wakeup pins are also used as P40 to P47. The pins which are not used as a
Edge detect
circuit
key-on wakeup pin must be disabled.
0: Key-on wakeup disable
1: Key-on wakeup enable
