THIS IS AN EXAMPLE OF A CDC CONVERSION COMPLETE INTERRUPT.
THIS TIMING EXAMPLE SHOWS THAT THE INTERRUPT OUTPUT HAS BEEN ENABLED TO BE ASSERTED AT THE END OF A CONVERSION CYCLE FOR
STAGE0, STAGE5, AND STAGE9. THE INTERRUPTS FOR ALL OTHER STAGES HAVE BEEN DISABLED.
STAGEx CONFIGURATION PROGRAMMING NOTES FOR STAGE0, STAGE5, AND STAGE9 (x = 0, 5, 9)
STAGEx_LOW_INT_EN (ADDRESS 0x005) = 0
STAGEx_HIGH_INT_EN (ADDRESS 0x006) = 0
STAGEx_COMPLETE_EN (ADDRESS 0x007) = 1

STAGEx_HIGH_INT_EN (ADDRESS 0x006) = 0
STAGEx_COMPLETE_EN (ADDRESS 0x007) = 0
SERIAL READBACK REQUIREMENTS FOR STAGE0, STAGE5 AND STAGE9. THIS READBACK OPERATION IS REQUIRED TO CLEAR THE INTERRUPT OUTPUT.
1. READ THE STAGE0_COMPLETE_STATUS_INT (ADDRESS 0x00A) REGISTER
2. READ THE STAGE5_COMPLETE_STATUS_INT (ADDRESS 0x00A) REGISTER
3. READ THE STAGE9_COMPLETE_STATUS_INT (ADDRESS 0x00A) REGISTER

NOTES
THIS IS AN EXAMPLE OF A SENSOR THRESHOLD INTERRUPT FOR A CASE WHERE THE LOW THRESHOLD LEVELS WERE EXCEEDED.
FOR EXAMPLE: THE SENSOR CONNECTED TO STAGE0 AND STAGE9 WERE CONTACTED AND THE LOW THRESHOLD LEVELS WERE EXCEEDED RESULTING
IN THE INTERRUPT BEING ASSERTED. THE STAGE6 INTERRUPT WAS NOT ASSERTED BECAUSE THE USER DID NOT CONTACT THE SENSOR CONNECTED TO
STAGE6.
