CM30 bit (Wait Control Bit)
When the CM30 bit is set to 1 (MCU enters wait mode), the CPU clock stops (wait mode). Since the XIN clock,
XCIN clock, and the on-chip oscillator clock do not stop, the peripheral functions using these clocks continue
operating. To set the CM30 bit to 1, set the I flag to 0 (maskable interrupt disabled).
The MCU exits wait mode by a reset or peripheral function interrupt. When the MCU exits wait mode by a
peripheral function interrupt, it resumes executing the instruction immediately after the instruction to set the
CM30 bit to 1.
When the MCU enters wait mode with the WAIT instruction, make sure to set the I flag to 1 (maskable interrupt
enabled). With this setting, interrupt handling is performed by the CPU when the MCU exits wait mode.
