C: When using the corresponding resource, the clock must be turned ON.
W: Inhibition of automatic ON/OFF of clock (SCU_REG register: by HPADC0_ACCESS_INHIBIT_REQ)
1*
In addition to this method, access to the SCU_RAM is possible by turning ON the CK_SCU_SCU_SEQ clock
during the assertion of an internal sequencer reset because the clock is supplied.
For information on CK_SCU_XOSC, CK_SCU_RC8M, CK_SCU_U32KL, and CK_SCU_U32KH, also refer
to the ADC (3.21) Chapter.
When multiple operations coincide, the corresponding clock must be turned ON from the CPU even when one
clock is "clock ON".
