Century Bit
Bits D7 and D6 of Clock Register 03h contain the
CENTURY ENABLE Bit (CEB) and the CENTURY
Bit (CB). Setting CEB to a '1' will cause CB to tog-
gle, either from a '0' to '1' or from '1' to '0' at the turn
of the century (depending upon its initial state). If
CEB is set to a '0,' CB will not toggle.
Output Driver Pin
When the AFE Bit and SQWE Bit are not set, the
IRQ/OUT/SQW pin becomes an output driver that
reflects the contents of D7 of the Control Register.
In other words, when D7 (OUT Bit) of address lo-
cation 08h is a '0,' then the IRQ/OUT/SQW pin will
be driven low.
Note:
The IRQ/OUT/SQW pin is an open drain
which requires an external pull-up resistor.
Preferred Power-on Default
When powering the device up from ground (0V),
the following register bits are set to a '0' state: ST;
AFE; and SQWE. The following bits are set to a '1'
state: OUT and 32kE (see Table 11, page 16).
Table 11. Preferred Power-on Default Values
Note: 1. If V
CC
falls to a voltage, 0V < V
CC
< 2.0V, these bits should be rewritten by the user.
