Bit Rate (Byte 3) – 32-bit value (Byte 0, Byte 1, Byte 2, Byte 3)
Example: Bit rate = 12,000,000 bps = 00B7 1B00
- This byte position will have a value of = 0x00
5
Bit Rate (Byte 2) – 32-bit value (Byte 0, Byte 1, Byte 2, Byte 3)
Example: Bit rate = 12,000,000 bps = 00B7 1B00
- This byte position will have a value of = 0x1B
6
Bit Rate (Byte 1) – 32-bit value (Byte 0, Byte 1, Byte 2, Byte 3)
Example: Bit rate = 12,000,000 bps = 00B7 1B00
- This byte position will have a value of = 0xB7
7
Bit Rate (Byte 0) – 32-bit value (Byte 0, Byte 1, Byte 2, Byte 3)
Example: Bit rate = 12,000,000 bps = 00B7 1B00
- This byte position will have a value of = 0x00

Chip Select to Data Delay (quanta of 100 s) – 16-bit value (low byte)
Example: If we have 500 s delay between the CS being asserted and the first byte of data, the value
will be 0x0005.
- This byte position will have a value of: 0x05
13
Chip Select to Data Delay (quanta of 100 s) – 16-bit value (high byte)
Example: If a 500 s delay between the CS being asserted and the first byte of data is required, the
value will be 0x0005.
- This byte position will have a value of: 0x00
14
Last Data Byte to CS (de-asserted) Delay (quanta of 100 s) – 16-bit value (low byte)
Example: If a 500 s delay between the last data byte sent and the CS being asserted is required, the
value will be 0x0005.
- This byte position will have a value of: 0x05
15
Last Data Byte to CS (de-asserted) Delay (quanta of 100 s) – 16-bit value (high byte)
Example: If a 500 s delay between the last data byte sent and the CS being de-asserted is required,
the value will be 0x0005.
- This byte position will have a value of: 0x00
