(2) Power save control register (PSC)
(3) Power save mode register (PSMR)
(4) Oscillation stabilization time selection register (OSTS)
Cautions 1. Be sure to clear bits 1 to 7 of the PSMR register to 0.
The power save control register (PSC) is a special register. Data can be written to this register only in
combination of specific sequences (refer to 3.4.8 Special registers).
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.
It 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 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.
