Section 21B Power-Down Modes [H8S/2626 Group]
21B.7.2 Hardware Standby Mode Timing
Figure 21B.4 shows an example of hardware standby mode timing.
When the STBY pin is driven low after the RES pin has been driven low, a transition is made to
hardware standby mode. Hardware standby mode is cleared by driving the STBY pin high, waiting
for the oscillation stabilization time, then changing the RES pin from low to high.
21B.8 Watch Mode
21B.8.1 Watch Mode
CPU operation makes a transition to watch mode when the SLEEP instruction is executed in high-
speed mode or sub-active 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 is internal registers, the data in internal RAM, and the statuses of the
internal supporting modules (excluding the SCI, ADC, HCAN) and I/O ports are retained.
