SERIAL INTERFACE READ/WRITE EXAMPLES
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)
• Stop signal
