5.2 When the Emulator Debugger Does Not Start Up Properly

(1) When the LEDs of the PC7501 Do Not Display Normally

Table 5.1 Errors LEDs show and their checkpoints

Error

Connection to

the user system

Checkpoint

LEDs do not light up.

Check that the power cable is connected.

See "2.5 Connecting the Power Supply for the Emulator" (page 24)
and the user's manual of the PC7501.

All LEDs remain lit.

Recheck the connection between the PC7501 and this product.

See "2.4 Connecting the PC7501" (page 23).

Target Status POWER LED
does not light up.

Connected Check

that

power (Vcc) is properly supplied to the user system and

that the user system is properly grounded.

Target Status CLOCK LED
does not light up.

Not connected

(1) Check that both the main and sub clocks of the emulator

debugger are not set to "EXT".

See the CLK command of the emulator debugger.

(2) Check the oscillation circuit in the emulator is oscillating.

See "2.11 Selecting Clock Supply" (page 38).

Connected

When the clock is supplied from an external oscillator, check that
the oscillator circuit in the user system is oscillating properly.

Target Status RESET LED does
not go out.

Connected

Check that the reset pin of the user system is pulled up.
