Figure 6: Register interpretation and PWM modes
MIXED OPERATION
Provided that functions do not overlap, two operating
modes can be used on one channel simultaneously.
The pins IA1 and IA2 are available as digital input or
output pins or current outputs if only the analog voltage
inputs, the voltage outputs or the current input function
at the particular channel is used. 4-wire PT temperature
sensors require a current output IAx and a differential
voltage input. A voltage output in conjunction with a
2- or 3-wire PT temperature sensor on one channel is
not possible. The counter (only available as the pri-
mary function) complies with the digital input, the PWM
complies with a digital output.
The primary function enables a fast data transfer via
SPI command. The secondary function is only able to
transfer data via register access and therefore is slower.
The following table shows all possible operating modes.
