tHardReset If a Soft Reset message fails, a Hard Reset is sent after tHardReset of
CRCReceiveTimer expiring
− − 5 ms
tHardReset
Complete
If the FUSB302B cannot send a Hard Reset within tHardResetComplete
time because of a busy line, then a I_HARDFAIL interrupt is triggered
− − 5 ms
tReceive This is the value for which the CRCReceiveTimer expires.
The CRCReceiveTimer is started upon the last bit of the EOP of the
transmitted packet
0.9 − 1.1 ms
tRetry Once the CRCReceiveTimer expires, a retry packet has to be sent out
within tRetry time. This time is hard to separate externally from tReceive
since they both happen sequentially with no visible difference in the CC
output
− − 75
ms
tSoftReset If a GoodCRC packet is not received within tReceive for NRETRIES then
a Soft Reset packet is sent within tSoftReset time.
− − 5 ms
tTransmit From receiving a packet, we have to send a GoodCRC in response within
tTransmit time. It is measured from the last bit of the EOP of the received
packet to the first bit sent of the preamble of the GoodCRC packet
