I found out, that I didn't keep my test program, but I wrote a small test program. It works on the 128MC802, but should be easy to convert to the 128GP202. This is left as an exercise to the reader
My hardware is setup like this:
VDD and AVDD to 3.3V
VSS+AVSS to GND
The cap is mounted on the board in a way, that I can't read the value
But I know that it is a tantalum cap, that is within the specs from the datasheet, which says 1-10uF (this is from the dsPIC33F/PIC24H Flash Programming Specification, 70152F, which should apply to your proc too).
There is not external xtal
MCLR is pulled up by a resistor.
I have tested this on my controller board for my robot. Using a multimeter, i measured a high level on 3-4 randomly selected pins. I admit that I a too lazy to test them all.
I hope you can use this. Good luck.
The code is:
#include "p33FJ128MC802.h"
_FOSCSEL(FNOSC_FRC);
_FOSC(FCKSM_CSECME & OSCIOFNC_ON & POSCMD_NONE);
int main(void)
{
//Setup ports
//===========
AD1PCFGL = 0xffff; //All analog capable pins in digital mode
TRISA = 0; //All pins output
TRISB = 0; //All pins output
PORTA = 0xFFFF; //All pins low
PORTB = 0xFFFF; //All pins low
while(1);
return 0;
}
