Responses

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

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

- Fill this byte position with: 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.

- Fill this byte position with: 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.

- Fill this byte position with: 0x04

SPI Mode

• 0x00 – SPI mode 0

• 0x01 – SPI mode 1
