Section 9 Power-Down Modes
9.2
9.2.1
The standby control register (STBCR) is an 8-bit readable/writable register that specifies the
power-down mode status. It is initialized to H'00 by a power-on reset via the RESET pin or due to
watchdog timer overflow.
Bit 7—Standby (STBY): Specifies a transition to standby mode.
Bit 7: STBY
0
1
Bit 6—Peripheral Module Pin High Impedance Control (PHZ): Controls the state of
peripheral module related pins in standby mode. When the PHZ bit is set to 1, peripheral module
related pins go to the high-impedance state in standby mode.
For the relevant pins, see section 9.2.2, Peripheral Module Pin High Impedance Control.
Bit 6: PHZ
0
1
Bit 5—Peripheral Module Pin Pull-Up Control (PPU): Controls the state of peripheral module
related pins. When the PPU bit is cleared to 0, the pull-up resistor is turned on for peripheral
module related pins in the input or high-impedance state.
For the relevant pins, see section 9.2.3, Peripheral Module Pin Pull-Up Control.
Bit 5: PPU
