Calibration is performed with each channel scan to remove offset and gain error. CJC
channel is also measured with each calibration.
On power-up, watchdog timeout, or software command. Processor boots within one
second of reset. Active low.
1.6 seconds nominal. Processor generates watchdog disable signal after boot-up.
Programmable for conversion to C or F
INTA# mapped to IRQn by PCIBIOS at boot time
Programmable
Dual port RAM when the processor mailbox has data.
