CHAPTER 2 PIN FUNCTIONS
2.2.16 P150 to P152, P157
P150 to P152 and P157 function as an I/O port. This port can also be used for A/D converter analog input, reference
voltage input, and operational amplifier input.

P157/ANI15
The following operation modes can be specified in 1-bit units.
(1) Port mode
P150 to P152 and P157 function as an I/O port. P150 to P152 and P157 can be set to input or output port in 1-bit
units using port mode register 15 (PM15).
(2) Control mode
P150 to P152 and P157 function as A/D converter analog input, reference voltage input, and operational amplifier
input.
(a) ANI8 to ANI10, ANI15
These are A/D converter analog input pins.
(b) AVREFM
This is the pin that inputs the negative reference voltage of A/D converter.
(c) AMP2+
This is the pin that the input voltage on the positive side of operational amplifier 2.
Cautions 1. P150/ANI8/AMP2+ to P152/ANI10 and P157/ANI15/AVREFM are set in the digital input (general-
purpose port) mode after release of reset.
2. When using at least one port of P150/ANI8/AMP2+ to P152/ANI10 and P157/ANI15/AVREFM as a
digital port, set AVDD0 to the same potential as EVDD or VDD.
2.2.17 COM0 to COM7
These are common outputs of LCD controller/driver.
2.2.18 SEGxx
These are segment outputs of LCD controller/driver.
Remark 78K0R/LF3: SEG0 to SEG30
78K0R/LG3: SEG0 to SEG39
78K0R/LH3: SEG0 to SEG53
2.2.19 VLC0 to VLC3
These are the pins for inputting a power supply voltage pin for driving the LCD.
