output mode by using PM15.
Port 15 is an 8-bit I/O port with an output latch. Port 15 can be set to the input mode or output mode in 1-bit units
This port can also be used for A/D converter analog input.
To use P150/ANI8 to P157/ANI15 as digital input pins, set them in the digital I/O mode by using the A/D port
To use P150/ANI8 to P157/ANI15 as digital output pins, set them in the digital I/O mode by using ADPC and in the
All P150/ANI8 to P157/ANI15 are set in the digital input mode when the reset signal is generated.
Figure 4-48 shows block diagram of port 15.
