• BITS: Bits Per Transfer
• CSAAT: Chip Select Active After Transfer
• CSNAAT: Chip Select Not Active After Transfer
• NCPHA: Clock Phase
• CPOL: Clock Polarity
32059K–03/2011
The BITS field determines the number of data bits transferred. Reserved values should not be used.
0: The Peripheral Chip Select Line rises as soon as the last transfer is achieved.
1: The Peripheral Chip Select does not rise after the last transfer is achieved. It remains active until a new transfer is requested
on a different chip select.
0 = The Peripheral Chip Select Line rises as soon as the last transfer is acheived
1 = The Peripheral Chip Select Line rises after every transfer
CSNAAT can be used to force the Peripheral Chip Select Line to go inactive after every transfer. This allows successful
interfacing to SPI slave devices that require this behavior.
0: Data is changed on the leading edge of SPCK and captured on the following edge of SPCK.
1: Data is captured on the leading edge of SPCK and changed on the following edge of SPCK.
NCPHA determines which edge of SPCK causes data to change and which edge causes data to be captured. NCPHA is used
with CPOL to produce the required clock/data relationship between master and slave devices.
0: The inactive state value of SPCK is logic level zero.
1: The inactive state value of SPCK is logic level one.
CPOL is used to determine the inactive state value of the serial clock (SPCK). It is used with NCPHA to produce the required
clock/data relationship between master and slave devices.
