28.6.6
This subsection describes the QADC status registers.
28.6.6.1 QADC Status Register 0 (QASR0)
QASR0 contains information about the state of each queue and the current A/D conversion. The bits in
this register are read anytime. For flag bits (CF1, PF1, CF2, PF2, TOR1, TOR2), writing a 1 has no effect;
writing a 0 clears the bit. For QS[9:6] and CWP, writes have no effect. Stop mode resets this register.
The end of a queue is identified in the following cases:

When execution is complete on the CCW in the location prior to the one
pointed to by BQ2
When the current CCW contains the end-of-queue code (channel 63) instead of a valid channel
