329 / 662 page ![]() Register Descriptions (ESSI0_BASE = $1FFE20, ESSI1_BASE = $1FFE00) Enhanced Synchronous Serial Interface (ESSI), Rev. 4 Freescale Semiconductor 12-29 Figure 12-16. Transmit Data Path (TSHFD = 1) 12.8.4 ESSI Receive Register (SRX) The SRX is a 16-bit, read-only register. It always accepts data from the Receive Shift Register (RXSR) as it becomes full. The data read occupies the most significant portion of the SRX register. The unused bits (least significant portion) are read as 0s. If the Receive Data Full Interrupt is enabled, the interrupt is asserted whenever the SRX register becomes full. When the Receive FIFO is also enabled, the Receive FIFO must be above its watermark before the interrupt is asserted. Figure 12-17. ESSI Receive Data Register (SRX) See Programmer’s Sheet on Appendix page B - 69 12.8.5 ESSI Receive FIFO Register (RXFIFO) The RXFIFO is a 8 × 16-bit FIFO register used to buffer samples received in the ESSI Receive Data Shift Register (RXSR). The receive FIFO is enabled by setting the RFEN bit of the SCR3 Control Register. Received data is then held in the FIFO if the data in the SRX has not yet been read.
