The ROM
test,
RAM
test,
and pC Kernel test runs automat-
ically. After the display test the test-program starts from
the beginning again. Use LOCAL/PRESET to step through
the different tests.
NOTE:
The
address test and dispiay test are described under
Levei 4 and Level
5
respectively,
but they cannot be
run before you have checked Level 6.

the functional levels in Figure
5-4.
For example Level 3 are
equal to Microcontroller
(3).
