Interrupt status bits are read only and sticky. Interrupts are described in Section 4.2. Registers at addresses 0x14–0x17 must not be part of a

control-port autoincremented read and must be read individually. See Section 4.14.1.

VMON_OVFL

xMON overflow. Indicates the overrange status in the VMON, IMON, or VPMON ADC signal path

0 (Default) No clipping has occurred anywhere in the ADC signal path

1 Clipping has occurred in the ADC signal path

The programming of IMON_SCALE may cause IMON_OVFL to be set.
