I am doing a project and unfortunately to change the project pic to the PIC18F27K40 the RDA stopped working, I tried to carry out a new project only with the RDA turning on an LED and it still does not work, could anyone help me?

Code: main.c
| Code: |
#include <main.h>
#INT_RDA
void RDA_isr(void)
{
output_toggle(PIN_B4);
}
void main()
{
enable_interrupts(INT_RDA);
enable_interrupts(GLOBAL);
while(TRUE)
{
}
}

Code:main.h
| Code: |
#include <18F27K40.h>
#device *ADC=10
#FUSES NOWDT //No Watch Dog Timer
#FUSES NOEXTOSC //External Oscillator not enabled
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#use delay(internal=64MHz)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=PORT1,enable=PIN_C5)

| You are going to need to use #pin_select. This processor uses pps and there is a sticky at the top of the forum page detailing its use. |

The example is in the post at the top of the forum.....
<http://www.ccsinfo.com/forum/viewtopic.php?t=55097>
For your chip:
| Code: |
#PIN_SELECT U1RX=PIN_C7
#PIN_SELECT U1TX=PIN_C6
#use rs232(baud=9600,parity=N,UART1,bits=8,stream=PORT1,enable=PIN_C5)
