Section 7 I/O Ports
In modes 5 to 7, P2DDR is a write-only register. Its value cannot be read. All bits return 1 when
read.
P2DDR is initialized to H'FF in modes 1 to 4, and to H'00 in modes 5 to 7, by a reset and in
hardware standby mode. In software standby mode it retains its previous setting. Therefore, if a
transition is made to software standby mode while port 2 is functioning as an input/output port and
a P2DDR bit is set to 1, the corresponding pin maintains its output state.
Port 2 Data Register (P2DR): P2DR is an 8-bit readable/writable register that stores output data
for Port 2. When port 2 functions as an output port, the value of this register is output. When a bit
in P2DDR is set to 1, if port 2 is read the value of the corresponding P2DR bit is returned. When a
bit in P2DDR is cleared to 0, if port 2 is read the corresponding pin logic level is read.
P2DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Port 2 Input Pull-Up MOS Control Register (P2PCR): P2PCR is an 8-bit readable/writable
register that controls the MOS input pull-up transistors in port 2.
In modes 5 to 7, when a P2DDR bit is cleared to 0 (selecting generic input), if the corresponding
bit in P2PCR is set to 1, the input pull-up transistor is turned on.
P2PCR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
