Lexicon 960L Service Manual page 43

CardID:
This number selects which reverb card to test. Legal values are 0 and 1, since only two reverb cards will be
supported. If only one card is present use the number 0.
Z80Id:
This specifies which Z80 on the card associated with a pair of Lexichip3's to test. Legal Values are 0 and 1.
Lexichip3Id:
This specifies which Lexichip3 associated with a particular Z80 to test. Legal values are 0 and 1.
NumRepeats:
This optional parameter specifies how many times to run the test. A value of 0 runs the test indefinitely (until
a key is pressed). Dots are shown on the display to indicate that the test is still running.
Notes:
- It is assumed that the following tests pass:
- DPRAM Test
- Z80BootTest
- Z80DpramTest
Details:
This command alternately loads two small programs into the DPRAM for the Z80, which move data to
(write), and from (read) Z80 memory space.
Lexichip3 ADF Test:
The syntax for the Lexichip3 ADF Test is: Lexichip3ADFTest CardId Lexichip3Id [NumRepeats].
This tests the ADF (Audio Data File) memory on the Lexichip3. The test begins by filling the ADF memory
with a specific data value then reading back the contents of each memory location, confirming the data
contained therein is correct. Values of 0, 0xFFFFFF, 0xAAAAAA and 0x555555 are tested.
This test confirms that the Z80 can access all of the Lexichip3's ADF memory space and that the memory
itself is operational.
Parameters:
CardID:
This number selects which reverb card to test. Legal values are 0 and 1, since only two reverb cards will be
supported. If only one card is present use the number 0.
Lexichip3Id:
This specifies which Lexichip3 to test. Legal values are 0 and 1.
NumRepeats:
This optional parameter specifies how many times to run the test. A value of 0 runs the test indefinitely (until
a key is pressed). Dots are shown on the display to indicate that the test is still running.
Notes:
- It is assumed that the following tests pass:
- DPRAM Test
- Z80BootTest
- Z80DpramTest
- Lexichip3 WCS Test
Details:
This command alternately loads two small programs into the DPRAM for the Z80, which move data to
(write), and from (read) Z80 memory space. Data is written into the ADF through direct memory "writes" to
the Lexichip3 but read back using the "Host Wide Data Latch".
TMIX Tests:
The following TMIX tests verify the operation of the 3 TMIX chips on the Reverb card.
