Table PMU (Power Management Unit)-43 shows the power supply control request registers. By writing "1" to
PMU_PW_CTL.POWER_CTRL_ON, power supply control starts according to the value of the power supply
control setting register (PWD_CTL, *_RAMMODE_SEL, ANA_PW_CTL).

3.4.3.6 Interrupt
The PMU has two types of interrupts, each of which allows the control of status read, clear, and mask. The two
interrupts (PMU_INT_STAT[1:0]) are ORed and sent to the CPU/DSP as INT_CAUSE0.PMU. For details, refer
to Section 3.3.2. The following describes the details of the two interrupts. Table PMU (Power Management
Unit)-44 shows a register list of the interrupts.

When a power supply control request is made with an incorrect setting of the power supply control
register (PWD_CTL, *_RAMMODE_SEL, ANA_PW_CTL), this changes to "1". At this time, the
power supply control is not performed. The reason for the error can be checked by PSW_CHECK. For
