Data Ready (Bar)
Indicates transceiver is powered and real time sense data is ready. (0 = Ready)
Note 3
Notes:
1. The response time for soft commands of the AFBR-57D7APZ is 100 msec as specified by the MSA SFF-8472.
2. Bit 6 is logic OR’d with the SFP TX_DISABLE input pin 3 ... either asserted will disable the SFP transmitter.
