Section 9 Power-Down Modes and Software Reset
9.2
9.2.1
The standby control register (STBCR) is an 8-bit readable/writable register that sets the power-
down mode. STBCR is initialized to H'00 by a power-on reset.
Bit 7—Standby (STBY): Specifies transition to standby mode.
Bit 7: STBY
0
1
Bits 6, 5, and 3—Reserved: These bits are always read as 0. The write value should always as 0.
Bit 4—Standby Crystal (STBXTL): Enables/disables crystal resonator in standby mode.
Bit 4: STBXTL
0
1
Bit 2—Module Stop 2 (MSTP2): Specifies halting the clock supply to the timer unit (TMU) in
the on-chip supporting module. When the MSTP2 bit is set to 1, the clock supply to the TMU is
halted.
