4.3.3 HALT-H Mode
In the HALT-H mode, HSCLK is forcibly stopped, the CPU stops, and only peripheral circuits remain in operation. Note
that the peripheral circuits in operation with the HSCLK stop operating in the HALT-H mode. See "4.1.7 Operation of
Each Function in Standby Mode" for operation of each function in the HALT-H mode.
When "1" is written in the HLTH bit of the SBYCON register, the operating state enters the HALT-H mode.
When a WDT interrupt or an interrupt enabled in registers IE0 to IE7 occurs, the HALT-H mode is released at the rising
edge of the next SYSTEMCLK, HSCLK is forcibly enabled, and the mode shifts back to the program run mode with the
SYSTEMCLK in the HSCLK state.
Even if the high-speed oscillation is disabled (ENOSC="0") and the low-speed clock (LSCLK) is selected
(SELSCLK="0") before entering the HALT-H mode, the high-speed oscillation is forcibly enabled (ENOSC="1") when
the HALT-H mode is released and the HSCLK is chosen for the SELSCLK (SELSCLK="1").
Figure 4-3 shows operation waveforms in the HALT-H mode.
