Section 9 I/O Ports
Port 3 Data Register (P3DR)
P3DR is an 8-bit readable/writable register, which stores the output data of port 3 pins (P35 to
P30).
P3DR is initialized to B'**000000 by a reset and in hardware standby mode. The previous state is
maintained in software standby mode.
Port 3 Register (PORT3)
Note: * Determined by the state of pins P35 to P30.
PORT3 is an 8-bit read-dedicated register, which reflects the state of pins. Write is disenabled.
Always carry out writing off output data of port 3 pins (P35 to P30) to P3DR without fail.
When P3DDR is set to 1, if port 3 is read, the values of P3DR are read. When P3DDR is cleared to
0, if port 3 is read, the states of pins are read out.
P3DDR and P3DR are initialized by a reset and in hardware standby mode, so PORT3 is
determined by the state of the pins. The previous state is maintained in software standby mode.
