[SOLVED] How disable or enable MCLR pin inside a function ?

MPLAB8.8V/PIC30F5011

Hi,

Normally MCLR pin enable/ disable is done when it is programmed, but I have a requirement to enable/disable at certain points of code execution.

What is the way to do it ?

void Switch_ON_Motor(void)
{

       _FBORPOR(MCLR_DIS);                  // Disable reset pin

	Latch_1 	= 	Enable;				// Enable Latch
	Relay_1		=	High;                         // R Phase
	Relay_2		=	High;                         // Y Phase
	Relay_3		=	High;                         // B Phase
	TimerDelay_10ms(1);
	Latch_1 	= 	Disable;				// Disable Latch
//	printf("\n\rSwitch ON Motor");	
}

My Error Log :

main.c: In function 'Switch_OFF_Motor':
main.c:298: error: section attribute cannot be specified for local variables
main.c:298: warning: ignoring space attribute applied to automatic _FBORPOR
main.c:298: warning: unused variable '_FBORPOR'

You didn't understand the meaning of attributes like _FBORPOR(). They translate to hardware fuses that are set during device programming.

Ok, I get it FVM,

Then is it there any other possible way so that no one can disturb my running motor by reset as it get disabled ?

Quite simple, if you don't want MCLR function temporarily, you must disable it permanently.
