Port 2 Data Direction Register (P2DDR)
P2DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 2. P2DDR cannot be read; if it is, an undefined value will be read.
Setting a P2DDR bit to 1 makes the corresponding port 2 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P2DDR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode. As the PPG and TPU are initialized
by a manual reset, the pin states are determined by the P2DDR and P2DR specifications.
Port 2 Data Register (P2DR)
P2DR is an 8-bit readable/writable register that stores output data for the port 2 pins (P2
P2DR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its prior
state after a manual reset, and in software standby mode.
