Section 19 Clock Pulse Generator
19.5
The frequency divider divides the duty-adjusted clock signal to generate the system clock ( ). The
frequency division ratio can be changed dynamically by modifying the value in DIVCR, as
described below. Power consumption in the chip is reduced in almost direct proportion to the
frequency division ratio. The system clock generated by the frequency divider can be output at the
19.5.1
Table 19.4 summarizes the frequency division register.
Table 19.4 Frequency Division Register
Note: * Lower 20 bits of the address in advanced mode.
19.5.2
DIVCR is an 8-bit readable/writable register that selects the division ratio of the frequency
divider.
DIVCR is initialized to H'FC by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 2—Reserved: These bits cannot be modified and are always read as 1.
