Struct TimeOfDay 

#[repr(C, packed(1))]
pub struct TimeOfDay {
    pub deci_seconds: RW<u8>,
    pub seconds: RW<u8>,
    pub minutes: RW<u8>,
    pub hours: RW<u8>,
}

A real-time clock is incorporated in the CIA, providing a timekeeping device more conducive to human needs than the microsecond precision of the interval timers. Time is kept in the American 12-hour AM/PM format. The TOD clock consists of four read/write registers: hours (with bit 7 acting as the AM/PM flag), minutes, seconds and tenths of a second. All registers read out in BCD format, thus simplifying the encoding/decoding process.

Fields
