ICSP not recognizing..

How accurate you want it?

Skimask changed the reload value... hence why you have higher value.

try...

@       __CONFIG _HS_OSC & _WDT_OFF & _LVP_OFF & _PWRTE_ON & _BODEN_ON

define OSC 20 

INT       VAR     PIR1.0  ' OVERFLOW flag
START   VAR     T1CON.0 ' START TMR1
LOAD     VAR     word

'------- Configurações iniciais -------------------- 
TRISA  = %00000000 ' PORTA
TRISB  = %00000000 ' PORTB 
TRISC  = %00000000 ' PORTC
TRISD  = %00000000 ' PORTD 
TRISE  = %00000000 ' PORTE 



OPTION_REG = %00000000
ADCON1 = %10001111  ' all digital
T1CON = %00000000   ' TMR1 1:1 prescaler
PIE1 = %00000001    ' Henable  TMR1 INT
START = 0
INT = 0
LOAD = 65404 '  INT. 36KHz
@TIMER1=TMR1L
TIMER1  var word EXT

'--------------------------------------------------- 
ON INTERRUPT GOTO SINUS

TIMER1=LOAD
INTCON = %11000000  ' enable global interrupt
START = 1 
PORTB.0 = 1
MAIN:      
        GOTO MAIN    

 
DISABLE
SINUS:  
           @ MOVE?CT 0, T1CON, TMR1ON
           TIMER1=TIMER1+LOAD
           @ MOVE?CT 1, T1CON, TMR1ON                       
           toggle PORTB.0
           INT = 0
RESUME
ENABLE

end

you should have something like 18KHz signal.. so yeah, your interrupt is still 36Khz... i just toggle the pin..

I tend to stay away of ON INTERRUPT when i need accuracy. ASM is the best while DT INST with PBP is still good enough for many purpose.
