The following paragraphs describes the clocks generated by the clock generating circuit.
(1) Main clock
(2) BCLK
(3) Peripheral function clock (f
The main clock is generated by the main clock oscillation circuit. After a reset, the clock is divided by
8 to the BCLK. The clock can be stopped using the main clock stop bit (bit 5 at address 0006
After the oscillation of the main clock oscillation circuit has stabilized, the drive capacity of the main
clock oscillation circuit can be reduced using the X

tion. This bit changes to “1” when shifting from high-speed/medium-speed mode to stop mode and at
a reset.
The internal clock

The main clock division select bit 0 (bit 6 at address 0006

The clock for the peripheral devices is derived by dividing the main clock by 1, 8 or 32. The peripheral
function clock is stopped by stopping the main clock or by setting the WAIT peripheral function clock
