Output Driver Pin
When the FT bit, AFE bit and watchdog register
are not set, the IRQ/FT/OUT pin becomes an out-
put driver that reflects the contents of D7 of the
Control Register. In other words, when D6 of loca-
tion 08h is a ‘0’, D7 of location 08h and 0Ah and
the watchdog register are a ‘0’ then the IRQ/FT/
OUT pin will be driven low.
Note: The IRQ/FT/OUT pin is an open drain which
requires an external pull-up resistor.
Initial Power-on Defaults
Upon initial application of power to the device, the
following register bits are set to a ‘0’ state: Watch-
dog Register; FT; AFE; ABE and SQWE. The fol-
lowing bits are set to a ‘1’ state: ST; OUT; and HT.
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.
