Assembled with MPLAB v6.13
This program continuously converts two ADC channels, AN0
& AN2 and writes the results out via SPI followed by a
control word 0xF9.
The software latency of the SPI transmission
is used to fulfill the aquire, conversion & wait time of
the ADC module for maximum data transmission rate.
transmission, therefore no watchdog is required.
SPI clock, SCK, is GP5 pin 2 idle low and data is valid on
the falling edge. SPI data out line, SDO, is PGP4 pin 3.
Use config word 0xE4 when programming
