Function
ter, check all STOP2 to STOP5 pins "H" that is enabled by STOPCR before the STOP mode is started (Note2,3).
a) STOP
Note 1: When the STOP mode released by the edge release mode (SYSCR1<RELM> = “0”), inhibit input from
Note 2: When the STOP pin input is high or STOP2 to STOP5 pins input which is enabled by STOPCR is low, execut-
Note 3: The input circuit of Key-on Wakeup input and Port input is separated, so each input voltage threshold value is
Note 4: STOP pin doesn’t have the control register such as STOPCR, so when STOP mode is released by STOP2 to
