Low Power Consumption
8.1
Overview
The RX610 Group has functions to reduce power consumption, including a multi-clock function, BCLK output stop
function, module stop function, and a function for transition to low power consumption mode.
Table 8.1 lists the specifications of low power consumption. Table 8.2 shows the conditions to shift to low power
consumption mode, states of the CPU and peripheral modules, and mode canceling method.
After the reset state, this LSI enters the normal program execution state, but modules except the DTC and DMAC do not
operate.

Description
Multi-clock function
The frequency division ratio is settable independently for the system clock (ICLK), peripheral
module clock (PCLK), and external bus clock (BCLK).
BCLK output stop function
BCLK output and high-output are selectable.
Module stop function
Functions can be stopped for each peripheral module.
Function for transition to low
power consumption mode
Transition to low power consumption mode is enabled to stop the CPU, peripheral modules, and
oscillator.
Four low power consumption
modes
Sleep mode
All-module clock stop mode
Software standby mode
Deep software standby mode
