2. When SOFRM = 1 is set
When the function controller function is selected, this module updates the frame number and
generates an SOFR interrupt if it detects a new SOF packet during full-speed operation. During
high-speed operation, however, this module does not update the frame number, or generates no
SOFR interrupt until the module enters the μSOF locked state. Also, the SOF interpolation
function is not activated. The μSOF lock state is the state in which μSOF packets with different
frame numbers are received twice continuously without error occurrence.
The conditions under which the μSOF lock monitoring begins and stops are as follows.
1. Conditions under which μSOF lock monitoring begins
2. Conditions under which μSOF lock monitoring stops

The SOFR interrupt is generated when SOF packets are damaged or missing. During high-
speed communication, interrupts are generated only if the first packet of a μSOF packet with
the same frame number is damaged or missing. (Corrupted or missing SOFs are recognized by
the SOF interpolation function. For details, see section 23.4.9, SOF Interpolation Function.)
USBE = 1
USBE = 0 (software reset), a USB bus reset is received, or suspended state is detected.
