DSP7 test items and display provided during execution.
1: CPU Interface (Data Bus) .................................................OK
2: CPU Interface (Chip Select) .............................................OK
3: CPU Interface (Address Bus) ............................................OK
4: E-RAM Interface (Data Bus) ............................................OK
5: E-RAM Interface (Address Bus) .......................................OK
6: SIO Connection (DSP7 → DSP6) ....................................OK
7: SIO Connection (DSP6 → DSP7) ....................................OK

NG: 1 ICxxx(1) [Soxx] → ICxxx(1) [Sixx]
1-8. SHARC Test
Contents Checks the communication between CPU and
SHARC.
Checks SHARC SDRAM (Address Bus, Data Bus).
Checks the FLAG line between CPU and SHARC.
Example of executing screen

x = Error bit
1-9. SLOT Test
Contents Checks the power voltage supplied to each interface
and SLOT of MY SLOT.
2SLOT check
Example of executing screen (In the case of SLOT1)
* The same screen appears for SLOT 2 as well but COM test is
for SLOT 1 only.
Display in case the check result is NG

Checking SLOT power voltage
Take measurement at each terminal of MY16-EX check jig using
a tester in the Manual mode for judgment.(For measurement,
connect a cable to the connector CN102 of EX.)
The COM test is applicable to SLOT1 only.
