TMP86C407MG
13. Key-on Wakeup (KWU)
TMP86C407MG have four pins P34 to P37, in addition to the P20 (INT5/STOP) pin, that can be used to exit STOP
mode.
When using these P34 to P37 pin’s input to exit STOP mode, pay attention to the logic of P20 pin.
In details, refer to the following section" 13.2 Control ".
