Bit
Force DLLP CRC error detection. This signal forces the MegaCore
function to check the next DLLP for a CRC error:
●
●
●
●
Force retry buffer. When asserted, this signal forces the retry
buffer to initiate a retry. These bits are reserved on the x8
MegaCore function.
Replace ACK by NAK. This signal replaces an ACK by a NAK with
following sequence number:
●
●
●
●
If unused, these bits should be hard-wired to 0 to remove unused
logic. These bits are reserved on the x8 MegaCore function.
Inject ECRC error on transmission. When asserted, this signal
generates an ECRC error for transmission.
Inject LCRC error on transmission. When asserted, this signal
generates an LCRC error for transmission. These bits are
reserved on the x8 MegaCore function.
Inject DLLP CRC error on transmission. Generates a CRC error
when transmitting a DLLP:
●
●
●
●
If unused, these bits should be hard-wired to 0 to remove unused
logic. These bits are reserved on the x8 MegaCore function.
00: normal mode
01: ACK/NAK
10: PM
11: flow control These bits are reserved on
the x8 MegaCore function.
00: normal mode
01: Same sequence number as the ACK
