LCD TEST?<R>
These tests used to verify the working of the LCD,
the keypad and
the USER RAM.
ENTER will run the test. ESCape will pass on the
the next test.
The LCD TEST fills the display with a character
sequence.
The KEYPAD TEST requires you to press all the
keys in sequence, left
to right, top to bottom. It cannot be completed
until all the keys
have been pressed in turn.
The DESTRUCTIVE RAM TEST fills USER
RAM with a Pseudo-Random number
sequence, and then compares it with the same
sequence. The original
contents are lost.
FUNC BURN = Chip Erase
<$&FUNCBURN>This command will Chip-Erase
FLASH PROMS.
FLASH PROMS can be overprogrammed, so it is
not certain that the user
would want to erase them first.
Chip Erase is not necessary with new or erased
PROMS and automatic
erasure would make programming take longer.
