pic18f87k40 Timer1 setting

[eyalbiton]

Hello members

PIC18F67K40

i try to operate timer1 without gate control.
seams it don't work.(timer0 work perfect).
i use 48mhz internal osc

i don't know what is wrong

PIE4.0=1 'TMR1 Overflow Interrupt Enable bit 
INTCON.6=1 'Peripheral Interrupt Enable bit 


TMR1CLK=%00000001   'Timer1 Clock Source Selection Register  Fosc/4
'TMR1CLK=%00000011   'Timer1 Clock Source Selection Register   HFINTOSC

;TMR1GATE=
T1GCON.7=0 'Timer Gate Enable bit
T1CON=00110100  'Timer1 Prescale 8 , Do not synchronize external clock input & off 
;T1CON=00110000  'Timer1 Prescale 8 , Synchronize external clock input with system clock & off 

PIR4.0=0 'CLEAR INT TIMER1


'****** TEST TIMER1 *******
T1CON.0=1 'TIMER 1 ON
WAIT2:
IF PIR4.0 THEN           'Timer1 INT
             T1CON.0=0    'Timer1 Off
             PIR4.0=0       'CLEAR INT  
             PORTE.5=PORTE.5 ^ 1    'led on/off
             TEMP=35536     '20MS /8  48MHZ
             TMR1H=TEMP.BYTE1
             TMR1L=TEMP.BYTE0      
             T1CON.0=1 'TIMER 1 ON  
             ENDIF


GOTO WAIT2

Have you defined temp as word ?- you do not show in your code.

Hi
Thanks for your replay.

i found the problem , i use wrong datasheet(PIC18 L_F26_27_45_46_47_55_56_57K40 ).
have different at datasheet PIC18(L)F67K40DataSheet40001841D

the Peripheral Interrupt iS PIR5.0 NO PIR4.0

IF SOME ONE NEED, TIMER1 SETTING FOR PIC18F67K40 without gate control
