Real Time Clock Timer
The real time clock timer is composed of a real time clock timer control register, sub second data register, second/
minute/hour data registers, 1/2 clock divider, 21-bit prescaler and second/minute/hour counters. Because the
MCU oscillation frequency operates on a given real time clock timer operation, a 4 MHz frequency is assumed.
The real time clock timer operates as a real world timer and provides real world time information.
