Description
USB Operation Clock Select 3 to 0
These bits control the on-chip PLL, which generates
the USB operation clock (48 MHz). When UCKS3 to
UCKS0 are 0000, the PLL circuit stops and thus the
USB operation clock must be selected according to
the clock source.
The on-chip PLL circuit starts operating after the USB
module stop 2 bit has been cancelled. In addition, the
USB operation clock is supplied to the UDC core after
the USB operating clock stabilization time has been
passed. The completion timing of the USB operating
clock stabilization time can be detected by the
CK48READY flag in UIFR3.
UCKS0 to UCKS3 muse be written while the USB
module stop 2 bit (MSTPB0) is 1.
