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 6 MHz for the USB using the following formula:
Where f
USB works ONLY with the MCU Clock frequencies of 12, 24, or 36 MHz. The Prescaler
values for these frequencies are 0, 1, and 2.
