TYPE
Receive STS-1 Telecom Bus - Channel 1 - Output Data Bus pin num-
ber 0:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 1 is enabled.
If STS-1 Telecom Bus (Channel 1) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 0:
STS1RXD_D0_1
This output pin along with STS1RXD_D_1[7:1] function as the STS-1
Receive (Drop) Telecom Bus - Output Data Bus for Channel 1. The
STS-1 Telecom Bus Interface will update the data via this output upon
the rising edge of STS1RXD_CK_1.
