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.
(See the IEIP2 SFR description in the Interrupt System section.)

0 to 255 decimal
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.
A2H
00H
No
0 to 127 decimal
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.
A3H
00H
No
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.
A4H
00H
No
0 to 59 decimal
Hours Time Register
This register is incremented in 1-hour intervals once TCEN in TIMECON is active. If the TFH bit (TIMECON.6)
is set to 1 the HOUR SFR counts from 0 to 23 before rolling over to 0. If the TFH bit is set to 0, the HOUR SFR
counts from 0 to 255 before rolling over to 0.
