Real Time Watch Timer
The real time watch timer is composed of a real time watch 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 watch timer operation, a 4 MHz frequency is
assumed. The real time watch timer operates as a real world timer and provides real world time information.
