23.1.16 Large Current Port Control Register (HCPCR)
HCPCR is a 16-bit readable/writable register that is used to control the large current port. It
controls bits PD10 to PD15, PE0 to PE3, PE5, PE6, PE9, PE11 to PE15 in SH7243, PD10 to
PD15, PD24 to PD29, PE0 to PE3, PE5, PE6, PE9, PE11 to PE15 in SH7285, and PD10 to PD15,
PD24 to PD29, PE0 to PE3, PE5, PE6, and PE9 in SH7286.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Port D Large Current Port High Impedance H
Selects whether to set the large current port of PD24
to PD29 to the high-impedance state regardless of the
setting of the PFC during the oscillation stop detection
and software standby mode.
0: set to the high-impedance state
1: do not set to the high-impedance state
The pin state is retained during the oscillation stop
detection when this bit is set to 1. See appendix A,
Pin States, for details on the software standby mode.
Port D Large Current Port High Impedance L
Selects whether to set the large current port of PD10
to PD15 to the high-impedance state regardless of the
setting of the PFC during the oscillation stop detection
and software standby mode.
0: set to the high-impedance state
1: do not set to the high-impedance state
The pin state is retained during the oscillation stop
detection when this bit is set to 1. See appendix A,
Pin States, for details on the software standby mode
