Real Time Clock Match Register (RTCMR)

Address: 0x8000.03C0, Read/Write

Definition: The Real Time Clock match register is a 32-bit read/write register,

which sets and reads the binary match time to RTC. Any value

written will be compared to the current binary time in the RTC, if

they match it will assert the RTCMI interrupt source. This register is

reset only by

nPOR.
