;function numbers may vary with different
;mask sets.
;set TCR1 to SYSCLK/4. At 16.778 MHz, this
;means that 1 TCR1 count = 238ns.
;HSQ bits = 0 for PWM function
;Channel Control Reg: Force pin low at
;initialization, use TCR1
;High time = $2000 TCR1 counts
;Period = $4000 TCR1 counts
;store starting addr of interrupt routine
;at location $200 ($80 X 4).Assume VBR = 0.
;interrupt level 6, vector $80
;mask interrupts below level 6
;enable interrupts on channel 0
;Host service request for initialization
;Give channel high priority
;clear interrupt request
;code in routine
;unused exceptions point here
