CONTROL 1 REGISTER

Address: 0x40001428, Reset: 0x01E0, Name: CR1
This register is a secondary control register that expands the level of WUT control, which is provided by CR0.
CR1 allows additional sticky interrupt sources in SR2 to be enabled. These sources fan into the WUT peripheral interrupt to optionally
tell the CPU when the WUT count has changed, when a prescaled (modulo 1) gated clock event has occurred to advance the WUT
count, when a trim boundary has occurred, when the 32-bit WUT count in CNT1 or CNT0 has rolled over, and when the modulo 60
version of the WUT count has rolled over.

Prescale Power of Two Division Factor for the WUT Base Clock. PRESCALE2EXP
defines the power of two by which the WUT base clock (nominally 32 kHz)
is prescaled before being used to count time by advancing the contents
of the CNT1 and CNT0 MMRs. In contrast, RTC1 can prescale the clock by
any power of two in the interval Bits[15:0] to use as its time base.
