FUNCTIONAL DESCRIPTION
Timer data configuration
I
Counter data in BCD code format
I
Automatic long/short month and leap-year adjustment
I
24-hour time display
I
LSB first write and read data
1. * bit: Optional write bits.
2. FDT bit: Supply voltage detect bit
The FDT bit is set to 1 when the voltage between VDD and VSS falls below 1.7 ± 0.3 V.
The FDT bit is reset to 0 for data reads longer than 48 bits. Note that the FDT bit is not reset to 0 for data
reads of 47 bits or less.
The read/write data bits should be should be set to 0. After the supply voltage is applied, the FDT bit
should be set to 0.
3. TM bit: Factory test bit. Should be set to 0 for normal use.
