Pin6,    TSCL    /  O  /    I2C Interface to digital temperature sensor Clock pin

Pin7,    TSDA    /  I/O  /    I2C Interface to digital temperature sensor Data pin

Pin8,     BS    /  I  /      Bus Interface selection pin   (NOTE 5-4)

Pin9,     BUSYN    / O /     Busy state output pin   (NOTE 5-3)

Pin10,    RSTN    / I /     Reset signal input. Active Low.

Pin11,    D/C    /  I  /      Data /Command control pin  (NOTE 5-2)

Pin12,    CSB    /  I  /     Chip select input pin  (NOTE 5-1)

Pin13,     SCL    / I  /     Serial Clock pin (SPI)

Pin14,     SDA    /  I  /     Serial Data pin (SPI)

Pin15,     VDDIO    /  P  /    Power Supply for interface logic pins. It should be connected with VDD

Pin16,     VDD    /  P  /    Power Supply for the chip

Pin17,     GND    /  P  /    Ground

Pin18,     VDDD    /  C  /     Core logic power pin VDDD can be regulated internally from VDD. A capacitorshould be connected between VDDD and VSS under all circumstances

Pin19,    VPP    /  P  /     Power Supply for OTP Programming

Pin20,     VSH    / C  /    Positive Source driving voltage 2

Pin21,     VGH    / C  /    Positive Gate driving voltage

Pin22,     VSL    / C   /    Negative Source driving voltage

Pin23,     VGL    / C  /     Negative Gate driving voltage

Pin24,     VCOM    /  C  /    VCOM driving voltage

I = Input Pin, O =Output Pin, I/O = Bi-directional Pin (Input/Output), P = Power Pin, C = Capacitor Pin

Note 5-1: This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CSB is pulled LOW.

Note 5-2: This pin is Data/Command control pin connecting to the MCU in 4-wire SPI mode. When the pin is pulled HIGH, the data at SDA will be interpreted as data. When the pin is pulled LOW, the data at SDA will be interpreted as command.

Note 5-3: This pin is Busy state output pin. When Busy is High, the operation of chip should not be interrupted, command should not be sent, e.g., The chip would put Busy pin High when - Outputting display waveform - Programming with OTP - Communicating with digital temperature sensor

Note 5-4: Bus interface selection pin

BS State        MCU Interface

L                    4-lines serial peripheral interface(SPI)

H                   3- lines serial peripheral interface(SPI) - 9 bits SP
