Last Data Byte to CS (De-asserted) Delay (quanta of 100 µs) – 16-bit value (low byte)
Example: If a 500 µs 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: 0x05
15
Last Data Byte to CS (De-asserted) Delay (quanta of 100 µs) – 16-bit value (high byte)
Example: If a 500 µs 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
16
Delay Between Subsequent Data Bytes (quanta of 100 µs) – 16-bit value (low byte)
Example: If a 500 µs delay between two consecutive data bytes is required, the value will be 0x0005.
- This byte position will have a value of: 0x05
17
Delay Between Subsequent Data Bytes (quanta of 100 µs) – 16-bit value (high byte)
Example: If a 500 µs delay between two consecutive data bytes is required, the value will be 0x0005.
- This byte position will have a value of: 0x00
18
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
19
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
