Name:
Access Type:
•
0 = SPI is in Slave mode.
1 = SPI is in Master mode.
•
0 = Fixed Peripheral Select.
1 = Variable Peripheral Select.
•
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 15 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 15 chip selects according to the following rules:
•
0 = The SPI operates at MCK.
1 = The SPI operates at MCK/32.
•
0 = Mode fault detection is enabled.
1 = Mode fault detection is disabled.
•
0 = Local loopback path disabled.
1 = Local loopback path enabled.
LLB controls the local loopback on the data serializer for testing in Master Mode only. MISO is internally connected to
MOSI.
