16.9. The Serial Interface Engine
The Serial Interface Engine (SIE) performs all low level USB protocol tasks, interrupting the processor
when data has successfully been transmitted or received. When receiving data, the SIE will interrupt the
processor when a complete data packet has been received; appropriate handshaking signals are automat-
ically generated by the SIE. When transmitting data, the SIE will interrupt the processor when a complete
data packet has been transmitted and the appropriate handshake signal has been received.
The SIE will not interrupt the processor when corrupted/erroneous packets are received.
16.10. Endpoint0
Endpoint0 is managed through the USB register E0CSR (USB Register Definition 16.17). The INDEX reg-
ister must be loaded with 0x00 to access the E0CSR register.
An Endpoint0 interrupt is generated when:
