Acoustic error messages
If an error is found, four different types of acoustic signals can be given:
- 2 sec. beep :
Non-critical error during normal use, to be corrected by the user.
- 1 /
2
sec. beep : Critical error, not of the CPU, that can be displayed.
- 1 /
2
sec. + 3 short beeps : Time out of the LCD (Error 21), an error that normally cannot be
displayed
- 6 short beeps : Critical CPU error (00 to 09). The microcontroller tries to show this
error on the LCD display.
List of errors with possible causes
Nr. Name Description Val Comment
1. Microcontroller core
00 err_CPU An error is found in the ALU or the
instructions of the microcontroller.
Check the microcontroller and the
software.
00
xx If value differs from
00, an incorrect
internal register bank
is addressed.
Six short beeps will
sound.
01 err_IntRAM An error is found in the internal
RAM of the microcontroller.
Probably the microcontroller needs
to be replaced. Otherwise check the
software. xx Value indicates at
which memory
location the error is
found.
Six short beeps will
sound.
02 err_RAM An error is found in the external
RAM.
Check the RAM and the
data/address lines. xx Value indicates in
which 256 byte block
the error is found.
Six short beeps will
sound.
03 err_Bankswitch Bankswitching of the program ROM
is not functioning properly.
Check the bankswitching hardware
and the appropriate processor lines. 01 Value shows the bank
number
(At present always
01).
Six short beeps will
sound.
04 err_ROM0 Incorrect checksum in the first 32
kByte of the EPROM. Check the
EPROM contents and the xx Value contains the
LSB of the 16 bit
checksum
