User Time Interval Select Register
User code writes the required time interval to this register. When the 8-bit interval counter is
equal to the time interval value loaded in the INTVAL SFR, the TII bit (TIMECON.2) is
set and generates an interrupt if enabled.

Hundredths Seconds Time Register
This register is incremented in 1/128 second intervals once TCEN in TIMECON is active. The
HTHSEC SFR counts from 0 to 127 before rolling over to increment the SEC time register.
