SPI_LSB_FIRST2

SPI least significant bit first.

0x0

1 = least significant bit shifted first for all SPI operations. On multibyte SPI

operations, addressing increments automatically.

0 = most significant bit shifted first for all SPI operations. On multibyte SPI

operations, addressing decrements automatically.

This bit must be accessed with all devices enabled and is not reset by

setting the SPI_SOFT_RESET1 or SPI_SOFT_RESET2 bit.

SPI_SOFT_RESET2

Self Clearing Soft Reset 1. Reset the SPI registers (self clearing).

0x0

This bit must be accessed with all devices enabled.

[4:3]

SPI_ADDR_MODE

13-bit addressing mode always enabled.

0x3

SPI_SOFT_RESET1

Self Clearing Soft Reset 1. Reset the SPI registers (self clearing).

0x0

This bit must be accessed with all devices enabled.

SPI_LSB_FIRST1

SPI least significant bit first.

0x0

1 = least significant bit shifted first for all SPI operations. On multibyte SPI

operations, addressing increments automatically.

0 = most significant bit shifted first for all SPI operations. On multibyte SPI

operations, addressing decrements automatically.

This bit must be accessed with all devices enabled and is not reset by

setting the SPI_SOFT_RESET1 or SPI_SOFT_RESET2 bit.
