Figure 43 shows the data streams when the TEMAP-84 is configured for the DS3 receive format. If the RXMFPO bit in the DS3 and E3 Master Unchannelized Interface Options register is logic 0, RFPO is valid and will pulse high for one RSCLK cycle on first bit of each M-subframe with alignment to the RDATO data stream. If the RXMFPO register bit is a logic 1 (as shown Figure 43), RMFPO is valid and will pulse high on the X1 bit of the RDATO data output stream. ROVRHD will be high for every overhead bit position on the RDATO data stream. Figure 44 shows the output data stream with RGAPCLK in place of RSCLK when the RXGAPEN bit in the DS3 and E3 Master Unchannelized Interface Options register set to logic 1. RGAPCLK remains high during the overhead bit positions.
