SPI Data Register User Manual excerpt: "Writes to this register will be blocked from when a data transfer starts to when the SPIF status bit is set, and the status register has not been read." SSP port: 8 byte rx/tx FIFO, max speed is pclk/2. You can fill FIFO at full speed, refill from interrupt, or poll FIFO register for state change. Joel
