GPIO-7

R/W

For write operation the GPIO pin operates as an output. Writing

a 1 to the GPIO-n bit sets the GPIO-N pin to high impedance.

Writing a 0 sets the GPIO-n pin to logic low.

For read operations the GPIO pin operates as an input. Read

the GPIO-n bit to receive the status of the GPIO-n pin.

The GPIO-n pin has 48-k

Ω input impedance to IOVDD.

7.6.11 Out-Of-Range ADC Thresholds: Address 0x80 through 0x93

The unipolar analog inputs (LV_ADC16 to LV_ADC20) and the local temperature sensor implement an out-of-

range alarm function. The Upper-Thresh and Lower-Thresh registers define the upper bound and lower bounds

for these inputs. This window determines whether the analog input or temperature is out-of-range. When the

input is outside the window, the corresponding CH-ALR-n bit in the Status Register is set to 1. For normal

operation, the value of the upper threshold must be greater than the value of lower threshold; otherwise, an

alarm is always indicated. The analog input threshold values are specified in straight binary format while the local

temperature ones are specified in two’s complement format.
