2.6 Power-Up Diagnostics

The power-up diagnostics provide a quick self-test facility for the Super

Card. They are executed following a hardware reset. The power-up

diagnostics test, briefly, all of the major hardware components to give

confidence that the card is working correctly.

The tests are run in the order that they are described below, and if all is

well control is passed to the application software. If any tests fail however,

the LCDs will display an error code for around 20 seconds whereupon the

card will restart and retest. Table 2-1 gives the error code meanings.
