6.16.1 Test Mode Error Interrupt Mask
Controls whether a Test Mode Error event flags the interrupt pin. A test mode error occurs when an inad-
vertent I²C write places the device in test mode.
MASKTSTMOD ERR In the event of a Test Mode Error event, Interrupt Pin will:
0
Be Flagged
1
Not be flagged
6.16.2 Serial Port Error Interrupt Mask
Controls whether the interrupt pin if flagged when any of the following parameters are changed without
first powering down the device (i.e., setting all Power Down ADCx and Power Down DACx bits):
• Serial Port Format: SP FORMAT[1:0]
•
Speed Mode: SPEED

6.16.3 Clocking Error Interrupt Mask
Allows or prevents a Clocking Error event from flagging the interrupt pin. See Section 4.8 for details.

6.16.4 ADCx Overflow Interrupt Mask
Allows or prevents an ADCx Overflow event from flagging the interrupt pin.
