There are two main methods of operating the HTADC12,

Open Loop and Closed Loop.

Open Loop

The HTADC can also be used in an open loop mode in which

the enable pins are held at a steady value and conversions are

triggered by RNC. The output data is available and read when

STS goes low. To trigger another conversion, only RNC has

to be driven low.

(1) CE is held high and NCS is held low.

(2) RNC is pulsed from a high to a low value which starts

the conversion. RNC returns high before the conversion

is completed.

(3) The STS signal will then go to a high value.

(4) When the conversion is complete, STS will go low indicating

the data is available on the output bus.

(5) The next conversion is started with another pulse on the RNC line.
