POWER SAVING FUNCTION
The following functions can save the power dissipation of the whole
system.
(1) Inactive system clock in wait mode
In the wait mode, if the internal peripheral devices need not to oper-
ate, when the system clock stop select bit at WIT (bit 3 of the particu-
lar function select register 1) = “1”, both of system clock fsys and
peripheral devices’ clock are inactive, and the power dissipation can
be saved.
For details, refer to the section on the standby function.
(2) Inactive oscillation circuit
When an externally-generated stable clock is input to pin XIN, the
power dissipation can be saved if both of the following conditions are
met:
the external clock input select bit (bit 1 of the particular function
select register 0) = “1”.
the oscillation driver circuit between pins XIN and XOUT is inactive.
At this time, the output level at pin XOUT is fixed to “H”. When not
using fPLL, also, the supply of
φBIU and φCPU restarts just after the
microcomputer returns from the stop mode, owing to an interrupt re-
quest occurrence. Therefore, an instruction can be executed just af-
ter the termination of the stop mode. For details, refer to the section
on the clock generating circuit and standby function.
(3) Disconnection from pin VREF
When not using the A-D converter, by setting the VREF connection
select bit (bit 6 of the A-D control register 1) to “1”, the resistor ladder
network of the A-D converter will be disconnected from the reference
voltage input pin (VREF). In this case, no current flows from pin VREF
to the resistor ladder network, and the power dissipation can be
saved. Note that, after the VREF connection select bit changes from
“1” (VREF disconnected) to “0” (VREF connected), be sure that a wait-
ing time of 1 s or more has passed before the A-D conversion
starts. For details, refer to the section on the A-D converter.
