16.2.1 Analog Interrupt Enable Register (AIE)
Register Description:
Analog Interrupt Enable Register
Register Name:
AIE
Register Address:
Module 05h, Index 05h
Bits 15 to 8: Reserved. Read returns 0.
Bit 7: Crystal Oscillator Failure (XTIE). See Section 15 for details on this bit.
Bit 6: DVDDIO Brownout Interrupt Enable (VIBIE). When set to 1, this bit allows an interrupt request to be generated when DVDDIO
falls below the specified threshold and VIBE is 1.
Bit 5: DVDD Brownout Interrupt Enable (VDBIE). When set to 1, this bit allows an interrupt request to be generated when DVDD falls
below the specified threshold and VDBE is 1.
Bit 4: AVDD Brownout Interrupt Enable (VABIE). When set to 1, this bit allows an interrupt request to be generated when AVDD falls
below the specified threshold and VABE is 1.
Bit 3: Echo Envelope Comparator Interrupt Enable (CMPIE). See Section 17 for details on this bit.
Bit 2: Echo Envelope Lowpass Filter FIFO Full Interrupt Enable (LFLIE). See Section 17 for details on this bit.
