CTC 94 Because interrupts are typically positive edge triggered the interrupt is not generated until OUT goes low and then high again CLOCK count 1 Mode 3 Square Wave Mode This mode is useful when it is necessary to generate a Square Wave output This mode is used most often for counter 0 which is the pre scalar for counters 1 and 2 Since the GATE of counter 0 is always enabled counter O will operate this mode Counters 1 and 2 can also use this mode to further divide the output of counter 0 the clock inputs provided by port C or an external event The OUT signal is HIGH after the control word is written After the COUNT value of N is written the OUT signal goes LOW on the negative edge of the next CLOCK pulse If N is an EVEN number OUT remains LOW for N 2 CLOCK pulses if N is an ODD number OUT is LOW for N 2 1 CLOCK pulses OUT then goes HIGH and remains HIGH until N equals 0 The value N is then automatically reloaded into the counter and the period repeats The GATE input being HIGH enables the counter If GATE input is LOW then counting is inhibited If GATE goes LOW while OUT is LOW OUT goes HIGH immediately The positive transition of GATE reloads the count value of N into the counter on the next CLOCK pulse The COUNT value is then decremented on subse quent CLOCK pulses Because interrupts are typically positive edge triggered the interrupt is not generated until OUT goes low and then

Even if they are connected with the Micro PC on there can be another failure mechanism Some serial and printer devices do not share the same power AC grounding The leakage can cause the serial or parallel signals to be 20 40V above the Micro PC ground thus damaging the ports as they are plugged in This would not be a problem if the ground pin is connected first but there is no guarantee of this Damage to the printer port chip will cause the serial ports to fail as they share the same chip Hot insertion Plugging cards into the card cage with the power on will usually not cause a problem Octagon urges that you do not do this However the card may be dam aged if the right sequence of pins contacts as the card is pushed into the socket This usually damages bus driver chips and they may become hot when the power is applied This is one of the most common failures of expansion cards Using desktop PC power supplies Occasionally a cus tomer will use a regular desktop PC power supply when bringing up a system Most of these are rated at 5V at 20A or more Switching supplies usually require a 20 load to operate properly This means 4A or more Since a typical Micro PC system takes less than 2A the supply does not regulate properly Customers have reported that the output can drift up to 7V and or with 7 8V voltage spikes Unless a scope is connected you may not see these transients Terminated backplanes Some customers try to
