CRC Calculation
CRC 0 = 0 (initial value)
CRC 1 = CRC_ TABLE [CRC 0 ^ Byte 1] = CRC_ TABLE [0x00 ^ 0x20] = 0x23
CRC 2 = CRC_ TABLE [CRC 1 ^ Byte 2] = CRC_ TABLE [0x23 ^ 0x01] = 0x9F
CRC 3 = CRC_ TABLE [CRC 2 ^ Byte 3] = CRC_ TABLE [0x9F ^ 0x06] = 0x8D
CRC 4 = CRC_ TABLE [CRC 3 ^ Byte 4] = CRC_ TABLE [0x8D ^ 0x03] = 0x93
D-2 Device ACK Packet
When the device receives supported commands comes from the host, and then will
response with following ACK:

CRC
ACC: The devices acknowledge status. Accept or Reject.
1: device accepts this request. (ACK; acknowledge)
0: device rejects this request. (NAK; negative acknowledge)
 The device sends the Nak packet is always 2 bytes. (NAK + CRC)
0: Reserve, Always 0.
1: Identifier, Always 1.
Device ID: Device id ranges from 0 to 31. (Please refer to device’s user manual)
CRC: Device always sends the CRC code to follow the last byte.
