Stop Mode:
The MCU enters stop mode if the STOP instruction is executed in active mode when TMA3 =
0. In this mode, the system oscillator stops, which stops all MCU functions as well.
Stop mode is terminated by a RESET input as shown in figure 11. RESET must be high for at least one t
RC
to stabilize oscillation (refer to the AC Characteristics section). When the MCU restarts after stop mode is
cancelled, all RAM contents are retained, but the accuracy of the contents of the accumulator, B register, W
register, X/SPX register, Y/SPY register, carry flag, and serial data register cannot be guaranteed.

Watch Mode:
The MCU enters watch mode if the STOP instruction is executed in active mode when
TMA3 = 1, or if the STOP or SBY instruction is executed in subactive mode.
Watch mode is terminated by a RESET input or a timer-A/
INT
0
interrupt request. For details on RESET
input, refer to the Stop Mode section. When terminated by a timer-A/
INT
0
interrupt request, the MCU
enters active mode if LSON is 0, or subactive mode if LSON is 1. After an interrupt request is generated,
the time required to enter active mode is t
RC
for a timer A interrupt, and T
X
(where T + t
RC
≤
T
X
≤
2T + t
RC
)
for an
INT
0
interrupt, as shown in figure 12.
Operation during mode transition is the same as that at standby mode cancellation (figure 10).
