9.5
9.5.1
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 9-4 shows
the port 4 pin configuration.
9.5.2
Table 9-8 shows the port 4 register configuration. Port 4 is an input-only port, and does not have a data direction register
or data register.
