Increment
1 (count starts) is written to TSTART bit in TRECR1 register
0 (count stops) is written to TSTART bit in TRECR1 register
Select any one of the following:
• Update second data
• Update minute data
• Update hour data
• Update day of week data
• When day of week data is set to 000b (Sunday)
Programmable I/O ports or output of f2, f4, or f8
When reading TRESEC, TREMIN, TREHR, or TREWK register, the count
value can be read. The values read from registers TRESEC, TREMIN,
and TREHR are represented by the BCD code.
When bits TSTART and TCSTF in the TRECR1 register are set to 0 (timer
stops), the value can be written to registers TRESEC, TREMIN, TREHR,
and TREWK. The values written to registers TRESEC, TREMIN, and
TREHR are represented by the BCD codes.
• 12-hour mode/24-hour mode switch function
