RCLKn clock period
RCLKn duty cycle, t
RPOSn/RNEGn data output delay after RCLKn

Figure 9. Line Side Receive Timing in Facility Loopback for Channel n
Control bit INVCO (bit 4 in XC1H) has no effect on which edge the data is transmitted.
The three signals for all channels are forced to a high impedance state when control bit
L3EN (bit 0 in 0C1H) is set to 0, or when a hardware or software reset occurs. Each chan-
nel’s output is forced to a high impedance state when control bit L3OEN (bit 0 in XC2H)
is set to 0. Facility loopback is enabled when control bit FLBK (bit 2 in XC1H) is set to 1.
