Twenty-Four Hour Select Bit.
Set by the user to enable the HOUR counter to count from 0 to 23.
Cleared by the user to enable the HOUR counter to count from 0 to 255.
The time interval counter continues to count after a reset when in hours/min/sec mode. If the part is in 24 hour
mode though, this bit is reset and the part now counts in 255 hour mode. The following code segment can be used
to set the TIC back into 24 hour mode after a RESET event.
NOTSE:
Interval Timebase Selection Bits.
Written by the user to determine the interval counter update rate.

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 the user software.
Time Interval Enable Bit.
Set by the user to enable the 8-bit time interval counter.
Cleared by the user to disable and clear the contents of 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 clear the time interval SFRs.
The time registers (HTHSEC, SEC, MIN and HOUR) can be written while TCEN is low.
