The USCL 8-bit Prescaler Register for USB is at
E1h. The USCL should be loaded with a value that
results in a clock rate of 6MHz for the USB using
the following formula:
USB clock input =
(FOSC / 2) / (Prescaler register value +1)
Where Fosc is the MCU clock input frequency.
Note: USB works ONLY with the MCU Clock fre-
quencies of 12, 24, or 36MHz. The Prescaler val-
ues for these frequencies are 0, 1, and 2.
