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
