The internal registers, timers and the interrupt controller of the processor are
tested.
The entire static RAM is ”read” tested and then ”write” tested, its previous
contents being overwritten as a result.
The checksums of the memories are determined.
In the FLASH TEST, the size and status of the FLASH memory are displayed
– for example, 128 k, ”empty” or ”prg.” for programmed).
In the RS232 interface test, data are transferred by the sender to the recipient
of the interface through a shorting plug.
