10F200 - MCLR as standard I/O
PostPosted: Wed Aug 15, 2012 10:43 am     Reply with quote
I'm using PIC10F200 and I want to use MCLR pin as normal I/O pin.
I declared into fuses NOMCLR but I can't use my GP3 yet.
Here is the code:
Code:

#include <10f200.h>
#use delay(clock = 4M)
#fuses NOMCLR,NOWDT,NOPROTECT

void main()
{
int port_b;
set_tris_b(0);
port_b = 0x0f; //GP0.....GP3 - set.
#byte port_b = 0x06; //thr address of PORT_B
}

From GP0 to GP2 I have high level output.
On GP3 I have high impedance.
One more question. How to set the oscillator: internal 4Mhz?

A brief datasheet reading is suggested:

Please note that GP3 is an input only pin.


PIC10F200 has 4 MHz internal oscillator as the only oscillator option. Nothing to setup.
