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.
