25.4.2 Interrupt Functions
Table 25.11 lists the interrupt generation conditions for this module.
When an interrupt generation condition is satisfied and the interrupt output is enabled using the
corresponding interrupt enable register, this module outputs the USB interrupt request signal to the
INTC.

When the function controller function is
selected:
• SOFRM = 0: When an SOF packet
with a different frame number is
received
• SOFRM = 1: When the SOF with
the μframe number 0 cannot be
received due to a corruption of a
packet
