18.2.3 SNOOZE mode
(1) SNOOZE mode setting and operating statuses
The SNOOZE mode can only be specified for CSIp, UARTq, or the A/D converter. Note that this mode can only be
specified if the CPU clock is the high-speed on-chip oscillator clock.
When using CSIp or UARTq in the SNOOZE mode, set up serial standby control register m (SSCm) before switching
to the STOP mode. For details, see 12.3 Registers Controlling Serial Array Unit.
When using the A/D converter in the SNOOZE mode, set up A/D converter mode register 2 (ADM2) before switching
to the STOP mode. For details, see 11.3 Registers Used in A/D Converter.
Remark 20 to 64-pin products: p = 00; q = 0; m = 0
80, 100, 128-pin products: p = 00, 20; q = 0, 2; m = 0, 1
The operating statuses in the SNOOZE mode are shown below.
