Provides both slave write and readback functionality
Standard mode at 100kbits/s
This serial interface is designed to allow multiple protocols to write and read from the
controller. It includes Block Read/Write, Block Index Read/Write, Byte Read/Write and Word
Read/Write. In general, the bytes must be accessed in sequential order from lowest to highest
byte. Each byte transferred must be followed by 1 acknowledge bit. A byte transferred without
acknowledged bit will terminate the transfer. The write or read block both begins with the
master sending a slave address and a write condition (0xD2) or a read condition (0xD3).
