Serial Interface Read/Write Examples

6.6.3
Write to one control register:
■ Start signal
■ Slave address byte (R/ W bit = low)
■ Base address byte
■ Data byte to base address
■ Stop signal
Write to four consecutive control registers:
■ Start signal
■ Slave address byte (R/ W bit = LOW)
■ Base address byte
■ Data byte to base address
■ Data byte to (base address + 1)
■ Data byte to (base address + 2)
■ Data byte to (base address + 3)
■ Stop signal
Read from one control register:
■ Start signal
■ Slave address byte (R/ W bit = low)
■ Base address byte
■ Start signal
■ Slave address byte (R/ W bit = high)
■ Data byte from base address
■ Stop signal
Read from four consecutive control registers:
■ Start signal
■ Slave address byte (R/ W bit = low)
■ Base address byte
■ Start signal
■ Slave address byte (R/ W bit = high)
■ Data byte from base address
■ Data byte from (base address + 1)
■ Data byte from (base address + 2)
■ Data byte from (base address + 3)
