#169252 - Timer 2 Interrupt Enable? |
Hi all,
I am working with P89V664 micro controller with SDCC .I am using the following function to configure timer 2 in capture mode and generate interrupt when an event occurs.
void init_ir_int(void)
{
/* initiate the hardware for IR cocommunication in interrupt
* mode */
/* Enable timer 2 in capture mode */
T2CON |= 0x01;
EXEN2 = 1;
EA = 1;
ET2 = 1;
}
The isr is as follows:
void isr_byte_recv(void) __interrupt 7
{
//the isr toggles led when TF2 overflows.
if (TF2 == 1) {
P1_5 = !P1_5; //P1_5 is connencted to an led.
}
TF2 = 0;
EXF2 = 0;
}
The interrupt is not generated! What's wrong here? I'd greatly appreciate any comments and suggestions. Regards, Sarma |
