Port 15 is an I/O port with an output latch. Port 15 can be set to the input mode or output mode in 1-bit units using port
mode register 15 (PM15).
This port can also be used for A/D converter analog input, reference voltage input, and operational amplifier input.
To use P150/ANI8/AMP2+ to P152/ANI10, P157/ANI15/AVREFM as digital input pins, set them in the digital I/O mode by
using the A/D port configuration register (ADPC) and in the input mode by using PM15. Use these pins starting from the
lower bit.
To use P150/ANI8/AMP2+ to P152/ANI10, P157/ANI15/AVREFM as digital output pins, set them in the digital I/O mode
by using ADPC and in the output mode by using PM15.
All P150/ANI8/AMP2+ to P152/ANI10, P157/ANI15/AVREFM are set in the digital input mode when the reset signal is
generated.
Figures 4-35 to 4-37 show block diagrams of port 15.
Caution Make the AVDD0 pin the same potential as the EVDD or VDD pin when port 15 is used as a digital port.
