WIDTH
; INTTC1 service switch initial setting
; Sets the TC1 mode and source clock
; IMF= “1”
; Starts TC1 with an external trigger at MCAP1 = 0
; INTTC1 interrupt, inverts and tests INTTC1 service switch
; Reads TC1DRB (High-level pulse width)
; Stores high-level pulse width in RAM
; Duty calculation
; IMF= “0”
; Enables INTTC1
; Reads TC1DRB (Cycle)
; Stores cycle in RAM
; INTTC1 Interrupt vector
Address set to convert INTTC1SW at each INTTC1
