Low power dissipation mode
Status Transition Of Internal Clock
Power dissipation can be reduced and low-voltage operation achieved by changing the count source for
internal clock
. Table 1.15 shows the operating modes corresponding to the settings of system clock
control registers 0 and 1.
After a reset, operation defaults to division by 8 mode. When shifting to stop mode, the main clock division select
bit 0 (bit 6 at address 000616) is set to “1”. The following shows the operational modes of internal clock
:
(1) Division by 2 mode
The main clock is divided by 2 to obtain the internal clock
.
(2) Division by 4 mode
The main clock is divided by 4 to obtain the internal clock
.
(3) Division by 8 mode
The main clock is divided by 8 to obtain the internal clock
. Note that oscillation of the main clock must
have stabilized before transferring from this mode to another mode.
(4) Division by 16 mode
The main clock is divided by 16 to obtain the internal clock
.
(5) No-division mode
The main clock is used as internal clock
.
(6) Low-speed mode
fC is used as internal clock
. Note that oscillation of both the main and sub clocks must have stabilized
before 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.
(7) Low power dissipation mode
fC is the internal clock
and the main clock is stopped.
