4.3.4 STOP Mode
The STOP mode is the state where LSCLK and HSCLK are forcibly stopped, and both the CPU and the peripheral circuit
which requires the clock stop operating. See "4.1.7 Operation of Each Function in Standby Mode" for operation of each
function in the STOP mode.
To enter the STOP mode, write "0x5n" then "0xAn" (n = arbitrary) to the STPACP register to enable the transition to the
STOP/STOP-D mode, then write "1" to the STP bit of the SBYCON register.
The STOP mode is released by the external interrupts, voltage level supervisor (VLS) or interrupt requests from the
analog comparator. It returns to the program run mode with the SYSTEMCLK chosen before entering the STOP mode.
Figure 4-4 shows STOP mode operation waveforms of the low-speed oscillation circuit.
Figure 4-5 shows STOP mode operation waveforms of the PLL oscillation circuit.
