Description
Reserved bits return an indeterminate value, and should never
be changed.
Current value at the time the register is accessed. No
read-modify-write protection is provided, so change with care.
This register is write-clear. Writing to it with any value clears the
register to 0. Clearing this register also clears the COUNTFLAG
bit of the SysTick Control and Status Register.
