Figure 5. Input Port Timing
Table 2 illustrates the data format selection for the input
port. For Hardware mode, the IFMTA0 (pin 1), IFMTA1
(pin 2), and IFMTA2 (pin 3) inputs are utilized to set the
input port data format for SRC A. IFMTB0 (pin 48), IFMTB1
(pin 47), and IFMTB2 (pin 46) are utilized to set the input
port data format for SRC B.
