Note 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 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.
