User manual
3.5.21 Trace clock divider register
3.5.22 SYSTICK clock divider register
3.5.23 USB clock source select register
This register configures the ARM trace clock. The trace clock can be shut down by setting
the DIV bits to 0x0.
Table 26.
This register configures the SYSTICK peripheral clock. The SYSTICK timer clock can be
shut down by setting the DIV bits to 0x0.
Table 27.
This register selects the clock source for the USB usb_clk. The clock source can be either
the USB PLL output or the main clock, and the clock can be further divided by the
USBCLKDIV register (see
The USBCLKUEN register (see
the update to take effect.
Remark: When switching clock sources, both clocks must be running before the clock
source is updated. The default clock source for the USB controller is the USB PLL output.
For switching the clock source to the main clock, ensure that the system PLL and the USB
PLL are running to make both clock sources available for switching. The main clock must
be set to 48 MHz and configured with the main PLL and the system oscillator. After the
switch, the USB PLL can be turned off.
