Single Time Interval Bit.
Set by the user to generate a single interval timeout. If set, a timeout clears the TIEN bit.
Cleared by the 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 the user to enable the 8-bit time interval counter.
Cleared by the user to disable the interval counter.
Time Clock Enable Bit.
Set by the user to enable the time clock to the time interval counters.
Cleared by the user to disable the clock to the time interval counters and reset the time interval SFRs to the last
value written to them by the user. The time registers (HTHSEC, SEC, MIN, and HOUR) can be written while TCEN
is low.
