; fMC = fBUS, FAST=0, DITH=0
; RECIRC=0, MCTOIE=0
; dual full h-bridge mode, left aligned,
; no channel delay
; disable motor controller
; define startup duty cycles
; define PWM period
; enable timer
; if PB=0, activate shutdown
; poll for timer counter overflow flag
; TOF set?
; yes, go to TIM_SR
; restore index register X
; if PB=0, enter shutdown routine
; restore index register X
; all mc configurations done?
; load new config’s
; leave sub-routine
; disable timer
; define startup duty cycle
; define startup duty cycle
; ensure that duty cycle registers are
; cleared for some time before disabling
; the motor controller
; define pwm period
; start new tx loop
; save byte counter
; clear TOF
; wait for new timer overflow
