Averaging Moving average, 1 to 16 samples, software-selectable
Calibration Calibration is performed with each channel scan to remove offset and gain error.
CJC channel is also measured with each calibration.

second of reset. Active low.
Watchdog timer 1.6 seconds nominal. Processor generates watchdog disable signal after boot-up.
Temperature units Programmable for conversion to C or F
Interrupts 2, 3, 4, 5, 6, or 7
Interrupt enable Programmable
Interrupt sources Dual port RAM when the processor mailbox has data.
