21.1.11 High-Current Port Control Register (HCPCR)
HCPCR is a 16-bit readable/writable register that is used to control the high-current ports (10 pins
(PD9, PD11 to PD15, and PE12 to PE15) in the SH7083, 12 pins (PD9, PD11 to PD15, PE9, and
PE11 to PE15) in the SH7084, 18 pins (PD9, PD11 to PD15, PD24 to PD29, PE9, and PE11 to
PE15) in the SH7085, and 24 pins (PD9, PD11 to PD15, PD24 to PD29, PE9, and PE11 to PE21)
in the SH7086).

MZIZDH 1
R/W Port D High-Current Port High-Impedance H
Selects whether or not the high-current ports PD24 to
PD29 are set to high-impedance regardless of the
PFC setting when detecting oscillation halt or in
software standby mode.
0: Set to high-impedance
1: Not set to high-impedance
If this bit is set to 1, the pin state is retained when
detecting oscillation halt. For the pin state in software
standby mode, refer to appendix A, Pin States.

R/W Port D High-Current Port High-Impedance L
Selects whether or not the high-current ports PD9 and
PD11 to PD15 are set to high-impedance regardless
of the PFC setting when detecting oscillation halt or in
software standby mode.
0: Set to high-impedance
1: Not set to high-impedance
If this bit is set to 1, the pin state is retained when
detecting oscillation halt. For the pin state in software
standby mode, refer to appendix A, Pin States.
