8.5
8.5.1
Port 4 is an 8-bit input-only port. 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). Port 4 pin functions are the
same in all operating modes. Figure 8.4 shows the port 4 pin configuration.
8.5.2
Table 8.8 shows the port 4 register configuration. Port 4 is an input-only port, and does not have a
data direction register or data register.
