CM1i : bit i of the address 0007
CM0i : bit i of the address 0006
Power dissipation can be reduced and low-voltage operation achieved by changing the count source for
BCLK. Table 1.11.4 shows the operating modes corresponding to the settings of system clock control
registers 0 and 1.
When reset, the device starts in division by 8 mode. The main clock division select bit 0 (bit 6 at address

from high-speed/medium-speed mode to stop mode, shifting to low power dissipation mode and at a reset.
When shifting from high-speed/medium-speed mode to low-speed mode, the value before high-speed/
medium-speed mode is retained. The following shows the operational modes of BCLK.
(1) Division by 2 mode
(2) Division by 4 mode
(3) Division by 8 mode
(4) Division by 16 mode
(5) No-division mode
(6) Low-speed mode
(7) Low power dissipation mode

The main clock is divided by 2 to obtain the BCLK.
The main clock is divided by 4 to obtain the BCLK.
The main clock is divided by 8 to obtain the BCLK. When reset, the device starts operating from this
mode. Before the user can go from this mode to no division mode, division by 2 mode, or division by 4
mode, the main clock must be oscillating stably. When going to low-speed or lower power consumption
mode, make sure the sub-clock is oscillating stably.
The main clock is divided by 16 to obtain the BCLK.
The main clock is divided by 1 to obtain the BCLK.

transferring from this mode to another or vice versa. At least 2 to 3 seconds are required after the sub-
clock starts. Therefore, the program must be written to wait until this clock has stabilized immediately
after powering up and after stop mode is cancelled.
