UIP - Update Cycle Status
This read-only bit is set prior to the update cycle. When
UIP equals 1, an RTC update cycle may be in progress.
UIP is cleared at the end of each update cycle. This bit
is also cleared when the update transfer inhibit (UTI)
bit in register B is 1.
Register B
Register B enables:
n
Update cycle transfer operation
n
Interrupt events
n
Daylight saving adjustment
Register B selects:
n
Clock and calendar data formats
All bits of register B are read/write.
Bit 3 - Unused Bit.
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
bq3285ED/LD 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
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
UTI - Update Transfer Inhibit
