Section 35. Serial Peripheral Interface (SPI) (Part II)
In the SPI Slave/Frame Master mode, the module acts as the SPI slave and takes its clock from
the other SPI module; however, it produces frame synchronization signals to control data
transmission (Figure 35-13). This mode is enabled by setting the MSTEN bit to ‘0’, the FRMEN
bit to ‘1’ and the SPIFSD bit to ‘0’.
The input SPI clock will be continuous in Slave mode. The SS1 pin will be an output when the
SPIFSD bit is low. Therefore, when the SPI1BUF is written, the module drives the SS1 pin to the
active state on the appropriate transmit edge of the SPI clock for one SPI clock cycle. Data will
start transmitting on the appropriate SPI clock transmit edge.
In the SPI Slave/Frame Slave mode, the module obtains both its clock and frame synchronization
signal from the Master module (Figure 35-14). This mode is enabled by setting MSTEN to ‘0’,
FRMEN to ‘1’ and SPIFSD to ‘1’.
In this mode, both the SCK1 and SS1 pins will be inputs. The SS1 pin is sampled on the sample
edge of the SPI clock. When SS1 is sampled at its active state, data will be transmitted on the
appropriate transmit edge of SCK1.
