CHAPTER 6 LOW POWER CONSUMPTION MODE
●
CPU intermittent operation selector
This selector selects the number of clock pulses the CPU is to be halted during CPU intermittent operation
mode.
●
Standby control circuit
The standby control circuit controls the CPU clock control circuit and the peripheral clock control circuit,
and turns the low power consumption mode on and off.
●
CPU clock control circuit
This circuit controls the clocks supplied to the CPU. This circuit controls the clocks supplied to peripheral
functions for the peripheral clock control.
●
Peripheral clock control circuit
This circuit controls the clocks supplied to peripheral functions.
●
Pin high-impedance control circuit
This circuit makes the external pins high-impedance when the microcontroller enters time-base timer mode
and stop mode.
For the pins with the pull-up option, this circuit disconnects the pull-up resistor when the microcontroller
enters stop mode.
●
Internal reset generation circuit
This circuit generates an internal reset signal.
●
Low power consumption mode control register (LPMCR)
This register is used to switch to and release standby mode and to set the CPU intermittent operation
function.
