When finished:
This bit is cleared when the first conversion command of the sequence from top of active
Sequence Command List is loaded
–
Mandatory Requirement:
- In all ADC conversion flow control modes a Restart Event causes bit RSTA to be set. Bit
SEQA is set simultaneously by ADC hardware if:
* ADC not idle (a conversion or conversion sequence is ongoing and current CSL not
finished) and no Sequence Abort Event in progress (bit SEQA not already set or set
simultaneously via internal interface or data bus)
* ADC idle but RVL done condition not reached
The RVL done condition is reached by one of the following:
* A “End Of List” command type has been executed
* A Sequence Abort Event is in progress or has been executed (bit SEQA already set or set
simultaneously via internal interface or data bus)
The ADC executes the Sequence Abort Event followed by the Restart Event for the
conditions described before or only a Restart Event.
- In ADC conversion flow control mode “Trigger Mode” a Restart Event causes bit TRIG
being set automatically. Bit TRIG is set when no conversion or conversion sequence is
ongoing (ADC idle) and the RVL done condition is reached by one of the following:
* A “End Of List” command type has been executed
* A Sequence Abort Event is in progress or has been executed
The ADC executes the Restart Event followed by the Trigger Event.
- In ADC conversion flow control mode “Trigger Mode” a Restart Event and a simultaneous
Trigger Event via internal interface or data bus causes the TRIG_EIF bit being set and ADC
cease operation.

Restart Event + CSL Exchange (Swap)
Internal Interface Signals: R LoadOK
Corresponding Bit Names: RSTA + LDOK
–
Function:
Go to top of active CSL (clear index register for CSL) and switch to other offset register for
address calculation if configured for double buffer mode (exchange the CSL list)
Requested by:
- Internal interface with the assertion of Interface Signal Restart the interface Signal
LoadOK is evaluated and bit LDOK is set accordingly (bit LDOK set if Interface Signal
LoadOK asserted when Interface Signal Restart asserts).
- Write Access via data bus to set control bit RSTA simultaneously with bit LDOK.
–
When finished:
Bit LDOK can only be cleared if it was set as described before and both bits (LDOK, RSTA)
are cleared when the first conversion command from top of active Sequence Command List
is loaded
–
Mandatory Requirement:
No ongoing conversion or conversion sequence
