ROUTINE FOR CAPACITIVE TOUCH SWITCH
//@ 8MHz = 125uS.
//Un-pressed switch value
//Difference between pressed
//and un-pressed switch
//amount to change
//from pressed to un-pressed
//storage for reading
// Enable the CTMU
// Set Edge status bits to zero
//drain charge on the circuit
//wait 125us
//end drain of circuit
//Begin charging the circuit
//using CTMU current source
//wait for 125us
//Stop charging circuit
//make sure A/D Int not set
//and begin A/D conv.
//Wait for A/D convert complete
//Get the value from the A/D
