dear all.
how to have a counter that will count for 1 minute...by using TMR1 in pic16f628a
i reer to use an interrupt
previously i use delay a minute from piclist code generator.
here the code fo 1 minute delay
how do i modify thsi code so that it can be use for TMR1
thanks in advance

Code:
; Delay = 60 seconds
; Clock frequency = 4 MHz
; Actual delay = 60 seconds = 60000000 cycles
; Error = 0 %
cblock
