8. I/O Ports
Port 4 Data Register (P4DR): P4DR is an 8-bit readable/writable register that stores output data
for port 4. When port 4 functions as an output port, the value of this register is output. When a bit
in P4DDR is set to 1, if port 4 is read the value of the corresponding P4DR bit is returned. When a
bit in P4DDR is cleared to 0, if port 4 is read the corresponding pin level is read.
Bit
Initial value
Read/Write
P4DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Port 4 Input Pull-Up MOS Control Register (P4PCR): P4PCR is an 8-bit readable/writable
register that controls the MOS input pull-up transistors in port 4.
Bit
Initial value
Read/Write
In 8-bit bus mode when a P4DDR bit is cleared to 0 (selecting generic input), if the corresponding
P4PCR bit is set to 1, the input pull-up transistor is turned on.
P4PCR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Table 8.3 summarizes the states of the input pull-ups in each operating mode.
