3-3.
PLLP2 Test (NO. 03)
Content:
Compares and checks registers (00h, 0Fh, 10h, 16h) of the PLLP2 by writing and reading them.
Example of execution screen
*** 03. PLLP2 ***
0x00 W/R OK!
0x0F W/R OK!
0x10 W/R OK!
0x16 W/R 0x16 W:0x0F R:0x00
EXIT:[ENTER]
Displayed at OK
Displayed at NG
Troubleshooting:
In case of NG, check the signal line, such as the address bus, data bus and control signal, connected between PLLP2
(DSP circuit board: IC502) and CPU (CPU circuit board: IC002).
Or the PLLP2 may be defective.
3-4.
DSP7 Test (NO. 04)
Content:
Writes and reads register of DSP7 to check the DataBus and AddressBus for normality.
SDRAM of DSP7 is written and read via registers to compare and check.
