Bit 6: Alarm Flag (AF). The alarm flag is set to a 1 when
the ETC value matches the alarm register. Once the AF
bit is set to a 1, it cannot be set to a 0. This bit is read-only.
Bit 5: Write Disable Flag (WDF). When the write disable
command is written to AAh twice at memory location 1Eh,
the WDF is set to a 1 and cannot be cleared or reset.
When WDF is set to a 1, the alarm, ETC, and event coun-
ter registers are read-only. This bit is read-only. The writes
need not be consecutive. Cycling power on VCC prior to
the second write terminates the reset sequence.
Bit 4: Write-Memory-Disable Flag (WMDF). When the
write-memory-disable command is written to F0h twice
at memory location 1Fh, the WMDF is set to a 1 and
cannot be reset or cleared. Once the WMDF is set to a
1, the 10-byte user memory becomes read-only. This bit
is read-only. The writes need not be consecutive. Cycling
power on VCC prior to the second write terminates the
reset sequence.
Bit 3: Alarm Output Select (AOS). If AOS is 0 and AF is
true, the DS1682 activates the ALARM output during an
event when AF becomes true. The DS1682 also activates
the ALARM output by pulling the pin low four times at
power-up, at the start and end of an event, or when the
ALARM pin is pulled low and released. This output mode
can be used to flash an LED or to communicate with
another device to indicate that an alarm has occurred. AP
has no affect on the output when AOS is 0.
If AOS is a 1 and AF is true, the ALARM output is constant
when the alarm is active. AP determines the polarity of
the output.
Bit 2: Reset Enable (RE). The reset enable bit allows the
device to be reset by enabling the reset command. The
sections of the DS1682 that are reset are then dependent
on the value in the WDF. With the WDF set to 0 and the
reset enable bit set to a 1, the reset command clears
the ETC, EEPROM, and event counter. When the reset
enable bit is set to a 0, the reset command is disabled.
Bit 1: Alarm Polarity (AP). When the alarm polarity bit
in the configuration register is set to 0, the ALARM output
is high impedance during the period that the value in the
ETC is less than the alarm register value. When the ETC
matches the alarm value, the ALARM pin is driven low.
If the AP bit is set to a 1, the ALARM output is driven
low during the period that the ETC is less than the alarm
value.
When the ETC matches the alarm value, the ALARM pin
becomes high impedance. The AP bit has no affect if AOS
is set to a 0.
Bit 0: Event Counter MSB (ECMSB). This bit is read-
only.
Configuration Register
Note: The configuration register is not stored in EEPROM until an event becomes inactive. RE does not need to be stored in
EEPROM to reset the device.
