Module Stop Control Register C (MSTPCRC)
Note:
Set the PRCR.PRC1 bit to 1 (write enabled) before rewriting this register.
Note 1. The corresponding MSTPC0 bit should not be set to 1 during access to the RAM. The corresponding RAM should not be
accessed while the MSTPC0 bit is 1.
Note 2. The MSTPC19 bit should be rewritten while the oscillation of the clock to be controlled by this bit is stable. For entering software
standby mode after rewriting this bit, wait for two cycles of the slowest clock among the clocks output by the oscillators actually
oscillating and execute the WAIT instruction.
DSLPE Bit (Deep Sleep Mode Enable)
The DSLPE bit enables or disables a transition to deep sleep mode.
When the CPU executes the WAIT instruction with the DSLPE bit set to 1 and the SBYCR.SSBY and
MSTPCRA.MSTPA28 bits meet specified conditions, the MCU enters deep sleep mode. For details, refer to
