Note 1.5-1: This pin (CSB) is the chip select input connecting to the MCU.
The chip is enabled for MCU communication: only when CSB is pulled LOW.
Note 1.5-2: This pin (DC) 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 (RST_N) is reset signal input. The Reset is active low.
Note 1.5-4: This pin (BUSY_N) is Busy state output pin. When Busy_N is
low operation of chip should not be interrupted and any commands should
not be issued to the module. The driver IC will put Busy_N pin low en the
driver IC is working such as:
- Outputting display waveform; or
- Communicating with digital temperature sensor
Note 1.5-5: This pin (BS) 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.
