EMGF indicates that PPG outputs are disabled by the emergency PPG output stop feature. To restart the
timer in that state, first make necessary settings for stopping the timer before canceling the emergency
PPG output stop state (by writing 1 to EMGR, bit7 of the TC7CR2) and then reconfiguring the control and
data registers to restart the timer.
