Output Payload Capability — RO. Hardwired to 3Ch indicating 60 word payload.
This field indicates the total output payload available on the link. This does not include bandwidth
used for command and control. This measurement is in 16-bit word quantities per 48 MHz frame.
The default link clock of 24.000 MHz (the data is double pumped) provides 1000 bits per frame, or
62.5 words in total. 40 bits are used for command and control, leaving 60 words available for data
payload.
00h = 0 word
01h = 1 word payload.
.....
FFh = 256 word payload.

Input Payload Capability — RO. Hardwired to 1Dh indicating 29 word payload.
This field indicates the total output payload available on the link. This does not include bandwidth
used for response. This measurement is in 16-bit word quantities per 48 MHz frame. The default link
clock of 24.000 MHz provides 500 bits per frame, or 31.25 words in total. 36 bits are used for
response, leaving 29 words available for data payload.
00h = 0 word
01h = 1 word payload.
