The response of the SIE can be summarized as follows:
The In and Out PID status is updated at the end of a trans-
action.
1. the SIE will only respond to valid transactions, and will ig-
2. the SIE will generate IRQ when a valid transaction is
3. an incoming Data packet is valid if the count is <= 10 (CRC
4. a Setup will be ignored by all non-Control endpoints (in
5. an In will be ignored by an Out configured endpoint and vice

The Setup PID status is updated at the beginning of the Data
packet phase.
The entire EndPoint 0 mode and the Count register are locked
to CPU writes at the end of any transaction in which an ACK
is transferred. These registers are only unlocked upon a CPU
read of these registers, and only if that read happens after the
transaction completes. This represents about a 1-µs window
to which to the CPU is locked from register writes to these USB
registers. Normally the firmware does a register read at the
beginning of the ISR to unlock and get the mode register infor-
mation. 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.
