Real-Time Clock and Non-Volatile RAM

The FX5653 contains a real-time clock compartment that maintains the date and
time in addition to storing configuration information about the computer system. It
contains 14 bytes of clock and control registers and 114 bytes of general purpose
RAM. Because of the use of CMOS technology, it consumes very little power and
can be maintained for long periods of time using an internal Lithium battery. The
contents of each byte in the CMOS RAM are listed below:
