18.4.1
To enter the standby mode, set the standby bit (SBY) to 1 in the standby control register
(SBYCR), then execute the SLEEP instruction. The LSI moves from the program execution state
to the standby mode. The standby mode greatly reduces power consumption by halting not only
the CPU, but the clock and on-chip peripheral modules as well. Some registers of the on-chip
peripheral modules are initialized, others are not (See table 18.3). As long as the specified voltage
is supplied, however, CPU register contents and on-chip RAM data are held. The I/O port state
(hold or high impedance) depends on the port high-impedance bit (HIZ) in the SBYCR. For details
on the states of these pins, see appendix B. Pin States.
