Receive STS-1 Telecom Bus – Channel 0 – Output Data
Bus pin number 6:
The exact function of this output pin depends upon whether
the STS-1 Telecom Bus Interface, associated with Channel 0
is enabled or not.
If STS-1 Telecom Bus (Channel 0) has been enabled –
STS-1 Receive Telecom Bus – Output Data bus pin number 6:
STS1RXD_D6_0
This
“STS1RXD_D_0[5:0]” function as the “STS-1 Receive (Drop)
