;FIRE SUBROUTINE
;Set Port D HIGH for 32uSec
;Save accumulator in temp location
;Clear accumulator
;Increment accumulator
;If accumulator equals three
;then 32uSec done, continue on
;else not done, keep looping
;Clear accumulator
;Set Port D low
;Restore accumulator
;If Bit G2 is high
;then go debounce from High
;else go debounce from Low
;DELAY SUBROUTINE
;Load Reg1 with 0F Hex
;Decr Reg1, If Reg1 not equal to 0
;then keep looping
;else return from delay routine
;DECREMENT THE TIMER BY THE DESIRED DELAY
;Load accumulator with value from T1RALO
;Subtract 7D Hex
;Store result in T1RALO
;Load accumulator with value from T1RAHI
;Subtract zero and borrow (if occurred)
;Reset carry flag
;Store result in T1RAHI
;Return from subtract routine
;INCREMENT THE TIMER BY THE DESIREd DELAY
;Load accumulator with value from T1RALO
;Add 7D Hex
;Store result in T1RALO
;Load accumulator with value from T1RAHI
;Add zero and carry bit
;Reset carry flag
;Store result in T1RAHI
;Return and skip from add routine
;TIMER Subroutine
;Start the timer
;If underflow (reload from R1A) occurred
;then go stop the timer
;else keep looping
;Stop the timer
;Reset the T1 source A pending flag
