Description

SPI Command Register

Fields

CPHA

RSPCK Phase

0 (0): Data is sampled at an odd edge and changes at an even edge.

1 (1): Data changes at an odd edge and is sampled at an even edge.

CPOL

RSPCK Polarity

0 (0): RSPCK in idle state is 0.

1 (1): RSPCK in idle state is 1.

BRDV

Bit Rate Division

0 (00): The base bit rate is selected.

1 (01): Two-divided base bit rate is selected.

2 (10): Four-divided base bit rate is selected.

3 (11): Eight-divided base bit rate is selected.

SSLKP

SSL Signal Level Hold

0 (0): All SSL signals are negated at the end of transfer.

1 (1): SSL signal level is held after the transfer ends until the next access starts.

LSBF

SPI LSB First

0 (0): MSB first

1 (1): LSB first

SPNDEN

SPI Next-Access Delay Enable

0 (0): Next-access delay is 1RSPCK + 5TCLK

1 (1): Next-access delay is the set value of the SPI next-access delay register (SPDECR.SPNDL).

SLNDEN

SSL Negation Delay Setting Enable

0 (0): [Master] SSL negation delay is 1RSPCK. [Slave in the TI-SSP] SSL negation delay is 1TCLK

1 (1): SSL negation delay is the set value of the slave select negation delay register (SPDECR.SLNDL).

SCKDEN

RSPCK Delay Setting Enable

0 (0): RSPCK delay is 1 RSPCK.

1 (1): RSPCK delay is the set value of the RSPCK delay register (SPDECR.SCKDL).

SPB

SPI Data Length

SSLA

SSL Signal Assertion

0 (Others): Setting prohibited

0 (000): SSL0

1 (001): SSL1

2 (010): SSL2

3 (011): SSL3
