Figure 23.8 shows an example of the SOFR interrupt output timing of this module. When the
frame number is updated or a damaged SOF packet is detected, the SOFR interrupt is generated.
The interrupt operation should be specified using the SOFRM bit in FRMNUM.
When the host controller function is selected, SOFRM = 1 should not be set.
1. When SOFRM = 0 is set

The SOFR interrupt is generated when the frame number is updated (intervals of
approximately 1 ms). Interrupts are generated by the internal interpolation function even if an
SOF packet is damaged or missing. During high-speed communication, interrupts are
generated at the timing at which the frame number is updated (intervals of approximately 1
ms).
