EV2740 KIT schematic:
17.2 ICE AND EV-KIT APPLICATION NOTIC
1. SN8ICE2K Plus 2 power switch must be turned off before you connect the EV2740 KIT to SN8ICE2K Plus 2.
2. Connect EV-KIT‟s CON1/CON2 to ICE‟s JP3/CON1.
3. SN8ICE2K Plus 2„s AVREFH/VDD jumper pin must be removed.
4. Turn on SN8ICE2K Plus power switch after user had finished step 1~3.
5. User observes EV-KIT‟s power LED (D1) is light after turn on SN8ICE2K Plus power switch. If LED (D1) is not light,
that means, user contact to SONIX‟s agent right now.
6. If user program select chip SN8P2743, JP24 open. Or user program select chip SN8P2742, JP24 short (Jumper).
7. It is necessary to connect 16MHz crystal in ICE for IHRC_16M mode emulation.
8. When ADC function enable. The ADM‟s bit 3 (FAVREFH) is set as High. P40O or JP18 (AVREFH) will be external
reference voltage input pin.
9. When ADC function enable. The ADM‟s bit 3 (FAVREFH) is set as Low. P40O will be analog signal input pin. JP18
(AVREFH) do not connect power device.
10. Observe ADC internal or external reference voltage is JP18(AVREFH).
11. The OP-Amp of SN8P2743 application circuit is as the below figure (OP-AMP connect).
