OIL Sensor Input - Block R


        What we have here is a means to detect oil pressure.  Its main function would be to server as a emergency shut down in case a loss of oil pressure should occur.  It can be configured to read a low pressure switch or piggy back on top of and electronic guage sensor line.  It can be read via the ADC and/or trigger an emergency interrupt.  This IRQ would be the only one in the entire code as the whole program is written interrupt free.
