Name:
Access Type:
• MSTR: Master/Slave Mode
0 = SPI is in Slave mode.
1 = SPI is in Master mode.
• PS: Peripheral Select
0 = Fixed Peripheral Select.
1 = Variable Peripheral Select.
• PCSDEC: Chip Select Decode
0 = The chip selects are directly connected to a peripheral device.
1 = The four chip select lines are connected to a 4- to 16-bit decoder.
When PCSDEC equals one, up to 16 Chip Select signals can be generated with the four lines using an external 4- to 16-bit
decoder.
The Chip Select Registers define the characteristics of the 16 chip selects according to the following rules:
*Note: The 16th state corresponds to a state in which all chip selects are inactive. This allows a different clock configuration
to be defined by each chip select register.
• DIV32: Clock Selection
0 = The SPI operates at MCK.
1 = The SPI operates at MCK/32.
• MODFDIS: Mode Fault Detection
0 = Mode fault detection is enabled.
1 = Mode fault detection is disabled.
• LLB: Local Loopback Enable

LLB
SPI_CSR0 defines peripheral chip select signals 0 to 3.
SPI_CSR1 defines peripheral chip select signals 4 to 7.
SPI_CSR2 defines peripheral chip select signals 8 to 11.
SPI_CSR3 defines peripheral chip select signals 12 to 15*.
