#155173 - Not getting response from P89LPC9107
Hi,

I am using LPC9107 for one of my application to control DC motor (ON/OFF) control through FET.

I am using ICP to program the microcontroller.

Programmer : USB-ICP from future Designs, Inc.

following is the code to check output at pin 0.7

#include <stdio.h>
#include "reg9107.h"

void main()
{
	TRIM |= 0x40;

	P0M1 &= 0x7F;
	P0M2 |= 0x80;

	EA = 1;

	P0 = 0x00;

	while(1);
}


I am able to program using ICP programmer and flash magic, flash magis says microcontroller is programmed.

but when i power up the microcontroller i can not see pin number 0.7 low, it is high. I tried to see clock out but i can not see even clock out too.

Please advice.

Thanks.
