Section 8 I/O Ports
Port 4 Register (PORT4)
PORT4 is an 8-bit read-only port. A read always returns the pin states. Writes are invalid.
8.5.3
Port 4 pins also function as A/D converter analog input pins (AN0 to AN7) and D/A converter
analog output pins (DA0 and DA1).
8.6
8.6.1
Port A is an 4-bit I/O port. Port A pins also function as address bus outputs. The pin functions
change according to the operating mode.
Port A has a built-in MOS input pull-up function that can be controlled by software.
Figure 8.5 shows the port A pin configuration.
