Set the AOUT/Comparators multiplexer to channel 6. The MISO read will be the results

of the channel 0 to channel 5 test.

Set the AOUT/Comparators multiplexer to channel 7. The MISO read will be the results

of the channel 0 to channel 6 test.

MOSI message will configure the device to test for a short between channel 1 and the

remaining channels. Previously verified is the integrity of channel 0 to 1. Set the

IBIAS/ISRC multiplexer to channel 2; set the AOUT/Comparators multiplexer to channel

3. The MISO read will be the results of the channel 0 to channel 7 test.

Clearing the MOSI Diagnostic Mode Message D7 places the AOUT pin in high impedance.

This feature allows the connection of multiple AOUT pins to a single A/D input. Only one

AOUT pin should enabled at any given time.
