Table 5-64. Command Register, Status Register, and TD Status Bit Interaction
Command Register, Status Register, and TD Status Bit Interaction
NOTES:
Note that if a NAK or STALL response is received from a SETUP transaction, a Time Out Error
will be reported. This causes the Error counter to decrement and the CRC/Time-out Error status bit
to be set within the TD Control and Status DWord during write back. If the Error counter changes
from 1 to 0, the Active bit is reset to 0 and Stalled bit to 1 as normal.
1. Only If error counter counted down from 1 to 0
2. Suspend mode can be entered only when Run/Stop bit is 0
