Receive STS-1 Telecom Bus – Channel 1 – Output Data
Bus pin number 0:
The exact function of this output pin depends upon whether
the STS-1 Telecom Bus Interface, associated with Channel 1
is enabled or not.
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
“STS1RXD_CK_1.
