PINT

SEG0~SEG31 are LCD driver outputs for LCD panel segments.

SEG0 is pin-shared with the SPI bus data output line, SDO.

SEG1 is pin-shared with the SPI bus data input line, SDI and the I

2C Bus

data line SDA.

SEG2 is pin-shared with the SPI bus clock line, SCK and the I

2C Bus clock

line SCL.

SEG3 is pin-shared with the SPI bus select line, SCS.

SEG4 is pin-shared with the Peripheral Clock line, PCLK.

SEG5 is pin-shared with the Peripheral Interrupt line, PINT.

The SEG0~SEG23 lines can be can be chosen to be either segment driv-

ers or CMOS outputs using control bits in the LCD control registers.

COM0~COM7

COM0~COM2 are the LCD common outputs.
