In the SPI Master/Frame Master mode, the SPI1 module generates both the clock and frame
synchronization signals, as shown in Figure 35-7. This configuration is enabled by setting the
MSTEN and FRMEN bits to ‘1’ and the SPIFSD bit to ‘0’.
In this mode, the serial clock is output continuously at the SCK1 pin regardless of whether the
module is transmitting. When SPI1BUF is written, the SS1 pin will be driven to its active state (as
determined by the FRMPOL bit) on the appropriate transmit edge of the SCK1 clock and remain
active for one data frame. If the FRMDLY control bit (SPI1CON2<1>) is cleared, the frame
synchronization pulse precedes the data transmission, as shown in Figure 35-8. If FRMDLY is
set, the frame synchronization pulse coincides with the beginning of the data transmission, as
shown in Figure 35-9. The module starts transmitting data on the next transmit edge of the SCK1.
