Register B
Register B enables:
n
Update cycle transfer operation
n
Square-wave output
n
Interrupt events
n
Daylight saving adjustment
Register B selects:
n
Clock and calendar data formats
All bits of register B are read/write.
DSE - Daylight Saving Enable
This bit enables daylight-saving time adjustments when
written to 1:
n
On the last Sunday in October, the first time the
bq3285E/L increments past 1:59:59 AM, the time
falls back to 1:00:00 AM.
n
On the first Sunday in April, the time springs
forward from 2:00:00 AM to 3:00:00 AM.
HF - Hour Format
This bit selects the time-of-day and alarm hour format:
1 = 24-hour format
0 = 12-hour format
DF - Data Format
This bit selects the numeric format in which the time,
alarm, and calendar bytes are represented:
1 = Binary
0 = BCD
SQWE - Square-Wave Enable
This bit enables the square-wave output:
1 = Enabled
0 = Disabled and held low
UIE - Update Cycle Interrupt Enable
This bit enables an interrupt request due to an update
ended interrupt event:
1 = Enabled
0 = Disabled
The UIE bit is automatically cleared when the UTI bit
equals 1.
AIE - Alarm Interrupt Enable
This bit enables an interrupt request due to an alarm
interrupt event:
1 = Enabled
0 = Disabled
PIE - Periodic Interrupt Enable
This bit enables an interrupt request due to a periodic
interrupt event:
1 = Enabled
0 = Disabled
