23.4.9
When the function controller function is selected and if data could not be received at intervals of 1
ms (when using full-speed operation) or 125 μs (when using high-speed operation) because an
SOF packet was corrupted or missing, this module interpolates the SOF. The SOF interpolation
operation begins when USBE = 1, SCKE = 1 and an SOF packet is received. The interpolation
function is initialized under the following conditions.
• Power-on reset
• Software reset
• USB bus reset
• Suspended state detected
Also, the SOF interpolation operates under the following specifications.
• 125 μs/1 ms conforms to the results of the reset handshake protocol.
• The interpolation function is not activated until an SOF packet is received.
• After the first SOF packet is received, either 125 μs or 1 ms is counted with the USB clock of
• After the second and subsequent SOF packets are received, interpolation is carried out at the
• Interpolation is not carried out in the suspended state or while a USB bus reset is being

after the last packet is received.)
