Stop Mode Cancellation by
STOPC
:
The MCU enters active mode from stop mode by inputting
STOPC
as well as by
R E SE T
. In either case, the MCU starts instruction execution from the starting address
(address 0) of the program. However, the value of the RAM enable flag (RAME: $021, bit 3) differs
between cancellation by
STOPC
and by
R E SE T
. When stop mode is cancelled by
R ESET
, RAME = 0;
when cancelled by
STOPC
, RAME = 1.
RESET
can cancel all modes, but
STOPC
is valid only in stop
mode;
STOPC
input is ignored in other modes. Therefore, when the program requires to confirm that stop
mode has been cancelled by
STOPC
(for example, when the RAM contents before entering stop mode is
