Explanation of first broadcast write command frame (D0 03 4C 00 FC 24):

  • D0 = broadcast write of one byte
  • 034C = register address
  • 00 = write value 0x00
  • FC24 = CRC

Explanation of first single device write command frame (90 00 03 08 00 13 DD):

  • 90 = single device write of one byte
  • 00 = device address
  • 0308 = register address
  • 00 = write value 0x00
  • 13DD = CRC

Explanation of first broadcast read command frame (C0 03 4C 00 F8 E4):

  • C0 = broadcast read
  • 034C = register address
  • 00 = read one byte of data
  • F8E4 = CRC
