Table 5-8. Port 4 Pin Functions
Usage
I/O port
Timer or clock
See section 8, 8-Bit Timer Module for details of the timer output select bits.
Pins of port 4 can drive a single TTL load and a 90-pF capacitive load when they are used as output
pins. They can also drive a Darlington pair.
Table 5-9 details the port 4 registers.
Table 5-9. Port 4 Registers
Name
Port 4 data direction register
Port 4 data register
Port 4 Data Direction Register (P4DDR)—H’FFB5
Bit
Modes 1 and 2
Mode 3
P4DDR is an 8-bit register that selects the direction of each pin in port 4. A pin functions as an
output pin if the corresponding bit in P4DDR is set to 1, and as an input pin if the bit is cleared to 0.
