Resets
At reset the ADC12B_LBA is disabled and in a power down state. The reset state of each individual bit is
listed within
Section 10.4.2, “Register Descriptions”
which details the registers and their bit-fields.
10.7
Interrupts
The ADC supports three types of interrupts:
•
Conversion Interrupt
•
Sequence Abort Interrupt
•
Error and Conversion Flow Control Issue Interrupt
Each of the interrupt types is associated with individual interrupt enable bits and interrupt flags.
10.7.1
ADC Conversion Interrupt
The ADC provides one conversion interrupt associated to 16 interrupt enable bits with dedicated interrupt
flags. The 16 interrupt flags consist of:
•
15 conversion interrupt flags which can be associated to any conversion completion.
•
One additional interrupt flag which is fixed to the “End Of List” conversion command type within
the active CSL.
The association of the conversion number with the interrupt flag number is done in the conversion
command.
10.7.2
ADC Sequence Abort Done Interrupt
The ADC provides one sequence abort done interrupt associated with the sequence abort request for
conversion flow control. Hence, there is only one dedicated interrupt flag and interrupt enable bit for
conversion sequence abort and it occurs when the sequence abort is done.
