17. Pin Function Controller (PFC)
17.1.11 High-Current Port Control Register (PPCR)
The high-current port control register (PPCR) is an 8-bit readable/writable register that is used to
control six pins (PE9/TIOC3B/SCK3/TRST*, PE11/TIOC3D/RXD3/TDO*,
PE12/TIOC4A/TXD3/TCK*, PE13/TIOC4B/MRES, PE14/TIOC4C/DACK0,
PE15/TIOC4D/DACK1/IRQOUT) of the high-current ports.
This register is not supported in the emulator. Bits are always read as undefined in the emulator.
Note: * Only in the SH7145

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
High-Current Port High-Impedance
This bit selects whether or not the high-current ports 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.
