23B.7.2 Hardware Standby Mode Timing
Figure 23B-4 shows an example of hardware standby mode timing.

23B.8 Watch Mode (U-Mask, W-Mask Version, H8S/2635 Group Only)
23B.8.1 Watch Mode
CPU operation makes a transition to watch mode when the SLEEP instruction is executed in high-
speed mode or subactive mode with SBYCR SSBY=1, LPWRCR DTON = 0, and TCSR (WDT1)
PSS = 1.
In watch mode, the CPU is stopped and supporting modules other than WDT1 are also stopped.
The contents of the CPU’s internal registers, the data in internal RAM, and the statuses of the
internal supporting modules (excluding the SCI, ADC, HCAN, and Motor control PWM) and I/O
ports are retained.
