Write to SPI1BUF
In the SPI Master/Frame Slave mode, the module generates the clock signal but uses the Slave
module frame synchronization signal for data transmission (Figure 35-10). This mode is enabled
by setting the MSTEN, FRMEN and SPIFSD bits to ‘1’.
In this mode, the SS1 pin is an input and is sampled on the sample edge of the SPI1 clock. When
it is sampled in its active state, data will be transmitted on the subsequent transmit edge of the
SPI1 clock. The interrupt flag, SPI1IF, is set when the transmission is complete. The user
application must make sure that the correct transmission data is loaded into the SPI1BUF before
the signal is received at the SS1 pin.
