Hello all

Today I play with " Instant Interrupts" thank's Darrel

For to begin I use blinky program
I want to augment the speed of blink light by loading a value
in TMR1H and TMR1L but the speed does not change

Rq:
I want not to change the value of the prescaler


code:

'********************
TMR1H = %11111111
TMR1L = %11111110
'********************

1CON = %110001 ; Prescaler = 8, TMR1ON

what is wrong please?
