6.4.1.2
When the low voltage reset or clock monitor failure signal is asserted the CRG asserts the system reset
signal. The CRG will deassert synchronously the system reset signal approximately 16420
EXTAL/CLK_CC clock periods after the deassertion of the low voltage reset or clock monitor failure
signal.
The CRG asserts the INT_CC# interrupt line and the low voltage reset interrupt flag, CRSR.LVIF, on the
rising edge of the low voltage reset signal. The CRG asserts the INT_CC# interrupt line and the clock
monitor failure interrupt flag, CRSR.CMIF, on the rising edge of the clock monitor failure signal.

The CRG deasserts the INT_CC# signal when CRSR.PRIF, CRSR.LVIF,
CRSR.CMIF and CRSR.ERIF bits are “0“.
