This is a preliminary specification and is subject to change.
9. Power Control
9.3.3.4 Exiting Wait Mode
The MCU exits wait mode by a reset or interrupt. Table 9.7 lists Resets and Interrupts to Exit Wait
Mode and Conditions for Use.
The peripheral function interrupts are affected by the CM02 bit. When the CM02 bit is 0 (peripheral
function clock f1 not turned off in wait mode), peripheral function interrupts can be used to exit wait
mode. When the CM02 bit is 1 (peripheral function clock f1 turned off in wait mode), the peripheral
functions using the peripheral function clock f1 stop operating, so that the peripheral functions
activated by external signals and the peripheral function clocks except f1 (fOCO40M, fOCO-F, fOCO-
S, fC, fC32) can be used to exit wait mode.
The fOCO-S is also used for the digital filter in the voltage detection circuit, so wait mode is exited
when the digital filter is disabled or when the fOCO-S is supplied.
