Module Stop
For details, refer to section 20.1.3, Module Stop
Control Registers A to C (MSTPCRA to MSTPCRC).
USB Module Stop 2
0: Cancels the stop state of the USB module
1: Places the USB module partly in the stop state.
Description
completely.
A clock is provided for the USB module completely.
Before clearing this bit, make sure to clear the
USBSTOP1 bit in EXMDLSTP. After this bit has
been cleared, the internal PLL circuit starts
operation. Registers in the USB module must be
accessed after the USB operating clock stabilization
time (the CK48READY bit in UIFR3 is set to 1) has
passed.
The internal PLL circuit and the most of the clocks in
the USB module stop operation. However, register
values in the USB module are maintained.
