9. Power-Down Modes
Bit 1—Clock Stop 1 (CSTP1): Specifies stopping of the peripheral clock supply to timer unit
(TMU) channels 3 and 4.
Bit 1: CSTP1
0
1
Description
Peripheral clock is supplied to TMU channels 3 and 4
(Initial value)
Peripheral clock supply to TMU channels 3 and 4 is stopped
Bit 0—Clock Stop 0 (CSTP0): Specifies stopping of the peripheral clock supply to the interrupt
controller (INTC). When this bit is set, PCIC and TMU channel 3 and 4 interrupts are not
detected.
Bit 0: CSTP0
0
1
Description
INTC detects PCIC and TMU channel 3 and 4 interrupts
(Initial value)
INTC does not detect PCIC and TMU channel 3 and 4 interrupts
9.2.6 Clock Stop Clear Register 00 (CLKSTPCLR00)
Clock stop clear register 00 (CLKSTPCLR00) is a 32-bit write-only register that is used to clear
