Note 1 . 5 -1: This pin (CS#) is the chip select input connecting to the MCU. The
chip is enabled for MCU communication: only when CS# is pulled
LOW.
Note 1.5-2: This pin (D/C#) is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data will be interpreted as data. When
the pin is pulled LOW, the data will be interpreted as command.
Note 1.5-3: This pin (RES#) is reset signal input. The Reset is active low.
Note 1.5-4: This pin (BUSY) is Busy state output pin. When Busy is High the
operation of chip should not be interrupted and any commands should
not be issued to the module. The driver IC will put Busy pin High when
the driver IC is working such as:
- Outputting display waveform; or
- Communicating with digital temperature sensor
Note 1.5-5: This pin (BS1) is for 3-line SPI or 4-line SPI selection. When it is
“Low”, 4-line SPI is selected. When it is “High”, 3-line SPI (9 bits
SPI) is selected.
