Standby Control Register 3 (STBCR3)
STBCR3 is a readable/writable 8-bit register used to select whether or not individual modules
operate in power-down mode. STBCR3 is initialized (to H'00) by a power-on reset, but retains its
previous value after a manual reset or a period in the standby mode. Only byte access is valid.

Port High Impedance
This bit selects whether the state of a specified pin is
retained or the pin is placed in the high-impedance
state. See Appendix A, Pin States to determine the
pin to which this control is applied.
Do not set this bit when the TME bit of WTSCR of the
WDT is 1. When setting the output pin to the high-
impedance state, set the HIZ bit with the TME bit
being 0.
0: The pin state is held in standby mode.
1: The pin state is set to the high-impedance state in
standby mode.
