If Bit 0 and Bit 1 of this register are both zero or one, this selects the default
interrupt mode, which gives the user an interrupt if the temperature goes above
the hot limit. T he interrupt will be cleared once the status register is read, but it
will again be generated when the next conversion has completed. It will continue to
do so until the temperature goes below the hysteresis limit.
A 0 on Bit 1 and a 1 on Bit 0 selects the one-time interrupt mode, which gives the
user an interrupt when the temperature goes above the hot limit. T he interrupt will
be cleared once the status register is read. Another interrupt will not be generated
until the temperature first goes below the hysteresis limit. No more interrupts will
be generated until the temperature again goes above the hot limit. T he correspond-
ing bit will be cleared in the status register every time it is read, but may not set
again when the next conversion is done. Note that this is the power-up default
mode.
A 1 on Bit 1 and a 0 on Bit 0 selects the comparator mode. T his gives an
INT
when the temperature exceeds the hot limit. T his
INT
remains active until the
temperature goes below the hot limit (no hysteresis), when the
INT
will become
inactive.
