MAX_
PAYLOAD_USER
RO, PKT_CON[3..0], Cyton-CXP
This is the maximum sized PCIe packet that will be generated by the Buffer Manager.
Writes to this register of values higher than MAX_PAYLOAD_PCIE will be ignored. The
coding is shown in the following table.
MAX_
PAYLOAD_PCIE
RO, PKT_CON[7..4], Cyton-CXP
This is the maximum sized PCIe write packet that can be generated by the Buffer Man-
ager for video data. This value is set by the PCIe enumeration. The coding for this field
is the same as listed under MAX_PAYLOAD_USER. Only values of 128 bytes to 4096
bytes are possible in PCIe, however, MAX_PAYLOAD_USER provides a few smaller
values (16 bytes to 64 bytes) for testing purposes only. MAX_PAYLOAD_PCIE is status
only and does not control internal logic. MAX_PAYLOAD_USER does control internal
logic.
DISABLE_PKT_
FLUSH_TIMER
R/W, PKT_CON[30], Cyton-CXP
Deactivate the timer that flushes video data to PCIe when the FIFO is inactive for an
extended period.
Note: This bit is for degging purposes only.
DISABLE_PKT_
GEN
R/W, PKT_CON[31], Cyton-CXP
Disable the generation of outbound PCIe video packets. This is a final stage disable.
The packet is actually generated by the logic as if it were going to be transmitted. This
means that all address's and other counters increment as if the packet were gener-
ated. However it is simply dropped afterwards.
Note: This bit is for debugging purposes only.
