The response of the SIE can be summarized as follows:
1. The SIE will only respond to valid transactions, and will ignore non-valid ones.
2. The SIE will generate an interrupt when a valid transaction is completed or when the FIFO is corrupted. FIFO corruption occurs
during an OUT or SETUP transaction to a valid internal address, that ends with a non-valid CRC.
3. An incoming Data packet is valid if the count is < Endpoint Size + 2 (includes CRC) and passes all error checking;
4. An IN will be ignored by an OUT configured endpoint and visa versa.
5. The IN and OUT PID status is updated at the end of a transaction.
6. The SETUP PID status is updated at the beginning of the Data packet phase.
7. The entire Endpoint 0 mode register and the Count register are locked to CPU writes at the end of any transaction to that
endpoint in which an ACK is transferred. These registers are only unlocked by a CPU read of these registers, and only if that
read happens after the transaction completes. This represents about a 1-
μ
s window in which the CPU is locked from register
writes to these USB registers. Normally the firmware should perform a register read at the beginning of the Endpoint ISRs to
unlock and get the mode register information. The interlock on the Mode and Count registers ensures that the firmware
recognizes the changes that the SIE might have made during the previous transaction.
