0x10 – Set SPI Power-up Transfer Settings – sub-command code

0x00 – Reserved

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 = 0x00

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 = 0x1B

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 = 0xB7

Bit Rate (Byte 0) – 32-bit value (Byte 0, Byte 1, Byte 2, Byte 3)

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

Example: If a 500 µs delay between the CS being asserted and the first byte of data is required,

the value will be 0x0005.

- Fill this byte position with: 0x05

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

Example: If a 500 µs delay between the CS being asserted and the first byte of data is required, the

value will be 0x0005.

- Fill this byte position with: 0x00

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.

- Fill this byte position with: 0x05

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.

- Fill this byte position with: 0x00

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.

- Fill this byte position with: 0x05
