After the start of command sequence transfer, the eQADC checks for the command sequence coherency
until the command sequence ends or one of the following conditions are true:
•
Command sequence is non-coherent.
•
CFIFO status changes from the TRIGGERED state
•
CFIFO underflow occurs
NOTE
The NCF flag is asserted if an external command buffer empty event is
detected at the same time the eQADC stops checking for the coherency of a
command sequence.
After command transfers restart or continue, the non-coherency hardware operate as if the command
sequence started from that point.
depicts how the non-coherency hardware operates when a
non-coherency event is detected.
NOTE
If MODE
n
is changed to disabled while a CFIFO is transferring commands,
the NCF flag for that CFIFO is not asserted.
NOTE
When the eQADC enters debug or stop mode while a command sequence is
executing, the NCF asserts if an empty external command buffer is detected
after debug or stop mode exits.
