A 1 written to the reset alarm CH_ clears the alarm, oth-
erwise no action occurs (Table 10). Deassert INT by
clearing all alarms or by initiating an SMBus alert during
an alarm condition (see the
SMBus Alert section)
The Delay 2, Delay 1, and Delay 0 bits set the speed of
monitoring by changing the delay between conver-
sions. Delay 2, 1, and 0 = 000 sets the maximum possi-
ble speed; 001 divides the maximum speed by
approximately 2. Increasing delay values further
divides the previous speed by two (Table 11).
INT_EN controls the open-drain INT output. Set INT_EN
to 1 to enable the hardware interrupt. Set INT_EN to 0
to disable the hardware interrupt output. The INT output
is high impedance when disabled or when there are no
alarms. The master can also poll the alarm status regis-
ter at any time to check the alarm status.
Repeat clocking channel threshold data up to the chan-
nel programmed by CS1 and CS0 (Table 12). For differ-
ential input mode, omit odd channels; the lower and
upper threshold data applies to channel pairs. There is
no need to clock in dummy data for odd (or even)
channels (Table 6).

When using delay = [0,0,0] in internal reference mode and
AIN3/REF configured as a REF output, the MAX1361/MAX1362
may exhibit a code-dependant gain error due to insufficient
internal reference drive. Gain error caused by this phenomenon
is typically less than 1%FSR (0.1F CREF in series with a 2k
Ω
resistor) and increases with a larger CREF. Avoid this gain error
by using an external reference, VDD, as a reference or use an
internal reference with AIN3/REF as an analog input (see Table
4). Alternatively, choose delay bits other than [0,0,0] to lower the
conversion rate.
