18.8 Control Registers
(1) Power save control register (PSC)
(2) Power save mode register (PSMR)
(3) Oscillation stabilization time selection register (OSTS)
Cautions 1. Be sure to clear bits 1 to 7 of the PSMR register to 0.
This is an 8-bit register that controls the standby function. The STP bit of this register is used to specify the
normal mode or IDLE/software STOP mode. The PSC register is a special register (refer to 3.4.8 Special
registers). Data can be written to this register only in a specific sequence so that its contents are not rewritten
by mistake due to a program hang-up.
This register can be read or written in 8-bit or 1-bit units.
This register is cleared to 00H after reset.
This is an 8-bit register that controls the operation status and clock operation in the power save mode.
This register can be read or written in 8-bit or 1-bit units.
This register is cleared to 00H after reset.
This is an 8-bit register that controls the operation status and clock operation in the power save mode.
Refer to 10.3 (1) Oscillation stabilization time selection register (OSTS).
2. The PSM bit is valid only when the STP bit of the PSC register is set to 1.
