2.3 Changing Hardware Settings

2.3.1 Selecting Clock Supply
You need to choose the X
MCU.
For normal use, select "Generated" in the Emulator tab of the Init dialog box of the emulator debugger and specify a frequency
you like to use for this clock supplied to an MCU.
You can change a frequency between 2.0 and 32.0 MHz by 0.1 MHz.

2.3.2 Using the Oscillator Circuit Board
Even when you have selected "Internal" on the Emulator tab of the emulator debugger's Init dialog box to specify an oscillator
circuit board, you need to enter a clock frequency.
With this emulator, no oscillator circuit board has been mounted when shipped from the factory. If you use a special frequency,
attach the oscillator circuit board following the procedure described below.
(1) Unscrew the five screws securing the E30A emulator, and remove the upper cover.
(2) The connector J1 for connecting an oscillator circuit board is in the corner of the board (around the DC power input
connector).
(3) Unscrew the screw which is used for securing an oscillator circuit board.
(4) Attach the oscillator circuit board you like to use, and secure the oscillator circuit board with the screw.
(5) Attach the upper cover and secure it with the five screws.
Note on Replacing the Oscillator Circuit Board:
When removing the upper cover or replacing the oscillator circuit boards, be sure to shut OFF the
power supply. Otherwise the internal circuit may cause a break.
Note on Using the Oscillator Circuit Board:
This product was inspected for the qualification of CE marking under factory shipment conditions (with
no oscillator circuit boards mounted in place). When using an oscillator circuit board for this product,
please be aware that depending on the oscillation frequency of the oscillator circuit board used,
radiation EMI standards (EN55022 Class A and FCC part 15 Class A) may be exceeded.
