Single Time Interval Bit
Set by user to generate a single interval timeout. If set, a timeout will clear the TIEN bit.
Cleared by user to allow the interval counter to be automatically reloaded and start counting again at
each interval timeout.
TIC Interrupt Bit
Set when the 8-bit Interval Counter matches the value in the INTVAL SFR.
Cleared by user software.
Time Interval Enable Bit
Set by user to enable the 8-bit time interval counter.
Cleared by user to disable and clear the contents of the interval counter.
Time Clock Enable Bit
Set by user to enable the time clock to the time interval counters.
Cleared by user to disable the clock to the time interval counters and clear the time interval SFRs.
The time registers (HTHSEC, SEC, MIN and HOUR) can be written while TCEN is low.
