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.

Seconds Time Register
This register is incremented in 1-second intervals once TCEN in TIMECON is active. The SEC SFR
counts from 0 to 59 before rolling over to increment the MIN time register.

0 to 59 decimal
Minutes Time Register
This register is incremented in 1-minute intervals once TCEN in TIMECON is active. The MIN SFR
counts from 0 to 59 before rolling over to increment the HOUR time register.
