Chip Select to Data Delay (quanta of 100 µs) – 16-bit value (low byte)

Example: If we have 500 µs 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

Chip Select to Data Delay (quanta of 100 µs) – 16-bit value (high byte)

Example: If we have 500 µs 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: 0x00

Last Data Byte to CS (de-asserted) Delay (quanta of 100 µs) – 16-bit value (low byte)

Example: If we have 500 µs delay between the last data byte sent and the CS being de-asserted,

the value will be 0x0005.

- This byte position will have a value of: 0x05

Last Data Byte to CS (de-asserted) Delay (quanta of 100 µs) – 16-bit value (high byte)

Example: If we have 500 µs delay between the last data byte sent and the CS being de-asserted,

the value will be 0x0005.

- This byte position will have a value of: 0x00

Delay Between Subsequent Data Bytes (quanta of 100 µs) – 16-bit value (low byte)

Example: If we have 500 µs delay between two consecutive data bytes, the value will be 0x0005.

- This byte position will have a value of: 0x05

Delay Between Subsequent Data Bytes (quanta of 100 µs) – 16-bit value (low byte)

Example: If we have 500 µs delay between two consecutive data bytes, the value will be 0x0005.

- This byte position will have a value of: 0x00

Bytes to Transfer per SPI Transaction – 16-bit value (low byte)

Example: If an SPI transaction of 1250 bytes long is required, the corresponding hex value

will be 0x04E2.

- This byte position will have a value of: 0xE2

Bytes to Transfer per SPI Transaction – 16-bit value (high byte)

Example: If an SPI transaction of 1250 bytes long is required, the corresponding hex value

will be 0x04E2.

- This byte position will have a value of: 0x04

SPI Mode

• 0x00 – SPI mode 0

• 0x01 – SPI mode 1

• 0x02 – SPI mode 2

• 0x03 – SPI mode 3
