16.2.3 Simplified RTC Minute/Second Counter (SRTCMAS)
This register is a special function register (SFR) used to show the minute/second data.
After enabling to write to the SRTCMAS register using the SRTCACP register, data can be written to the SRTCMAS
register.
The SRTCMAS register is initialized only by the power-on reset.
If data is written only to one of the independent minute or second counters, the value in the other counter will not be
changed.
It is recommended that data is written to the SRTCMAS register in units of 16 bits.
Address:
0xF0CA (SRTCSEC/SRTCMAS), 0xF0CB (SRTCMIN)

PORSTAT
This bit is used to indicate the simplified RTC operating status.
The initial value of PORSTAT bit is "1".
To write data to the SRTCMAS register, write "0" to the PORSTAT bit. When "1" is written
to the PORSTAT bit, the initial value is written to the SRTCMAS register.
0: Normal operation
1: After power-on reset, no data has been written to the SRTCMAS register, or data
outside the configurable range has been written to the SRTCMAS register
14 to 8
MIN40 to
MIN1
These bits are used to store the minute data.
Count up as soon as the second counter (SRTCSEC) changes from 59 to 00.
The SRTCMIN register indicates 0 to 59 minutes as a decimal number. MIN40 to MIN10
bits indicate a tens place, whereas MIN8 to MIN1 bits indicate a ones place.
MIN40 to MIN10 bits can be written within the range of 0 to 5, whereas MIN8 to MIN1 bits
can be written within the range of 0 to 9.

These bits are used to store the second data.
Count up at the falling edge of the T1HZ signal.
The SRTCSEC register indicates 0 to 59 minutes as a decimal number. SEC40 to SEC10
bits indicate a tens place, whereas SEC8 to SEC1 bits indicate a ones place.
SEC40 to SEC10 bits can be written within the range of 0 to 5, whereas SEC8 to SEC1 bits
can be written within the range of 0 to 9.
