(3) Clearing stop mode and wait mode
(4) BCLK in returning from wait mode or stop mode
Table 2.14.1. Interrupts available for clearing stop mode and wait mode
The stop mode and wait mode can be cleared by generating an interrupt request, or by resetting
hardware. Set the priority level of the interrupt to be used for clearing, higher than the processor
interrupt priority level (IPL), and enable the interrupt enable flag (I flag). When an interrupt clears a
mode, that interrupt is processed. Table 2.14.1 shows the interrupts that can be used for clearing a
stop mode and wait mode.
(a) Returning from wait mode
(b) Returning from stop mode
The processor immediately returns to the BCLK, which was in use before entering wait mode.
CM06 is set to “1” when the device enters stop mode after selecting the main clock for BCLK. CM17,
CM16, and CM07 do not change state. In this case, when restored from stop mode, the device starts
operating in divided-by-8 mode.
When the device enters stop mode after selecting the subclock for BCLK, CM06, CM17, CM16, and
CM07 all do not change state. In this case, when restored from stop mode, the device starts operat-
ing in low-speed mode.
