User guide for STK55C322/324 emulator
1.
Connectors :
1.1
J1 is a phone jack connector. Please connect to a voltage adapter with 7 Vdc output.
1.2
JP1 and JP2 should be connected to external LCD panel or LCD simulator.
1.3
JP3 is I/O port connector.
1.4
JP4 is for external speaker.
2.
Switch setting :
2.1
S1 set the CPU compatible to standard CPU or KC5713 CPU.
2.2
S2 select internal CPU or external CPU.
INT. CPU – In this mode, the internal CPU is enabled. The external CPU or ICE
should be removed.
EXT. CPU – In this mode, the internal CPU is disabled. An external CPU or ICE
should be installed in U1.
2.3
S3 is power switch for EV chip.
IC ON – The Vcc is connected to the KC5731 IC.
IC OFF -- The Power pin of KC5731 IC is floating. The IC operating current can be
measured by connecting a current meter between the two points of TP2 or
between J7 and J8.
2.4
S4 is oscillator selection switch.
XTAL -- Use 32768HZ crystal oscillator.
RC
-- Use RC oscillator. R3 will decide the oscillation frequency. In this mode, the
Y1 crystal should be removed. The frequency can be checked at XOSC2.
2.5
S5 is reset switch.
2.6
S6 is speaker selection switch.
INT. SPK -- On board speaker is selected.
EXT. SPK -- External speaker is selected. The customer’s speaker can be add
between J9 and J11.
2.7
S7 is power switch.
EXT. PWR
-- Add DC power from J2 (GND) and J3 (Vdd). The voltage range is
