5.9 PORT 7
input pins (ANI0 to ANI7).
5.9.1 Hardware Configuration
150
Port 7 is an 8-bit input/output port. In addition to operating as an input/output port, it also operates as the A/D converter analog
Input/output can be specified bit-wise by means of the port 7 mode register (PM7).
Pin levels can be read or tested at any time irrespective of dual-function pin operations.
When RESET is input, port 7 is set as an input port (output high-impedance state), and the output latch contents are undefined.
The port 7 hardware configuration is shown in Figure 5-61.
