Receive STS-1 Telecom Bus – Channel 1 – Output Data
Bus pin number 2:
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 2:
STS1RXD_D2_1
This output
“STS1RXD_D_1[1:0]” 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.
