18.8.5.3 QADC Control Register 2<br />

Control register 2 (QACR2) is the mode control register for the operation<br />

of queue 2. Software specifies the queue operating mode of queue 2<br />

and may enable a completion and/or a pause interrupt. Most of the bits<br />

are typically written once when the software initializes the QADC and not<br />

changed afterward.<br />

Stop mode resets the register ($007f)<br />

CIE2 — Queue 2 Completion Software Interrupt Enable Bit<br />

CIE2 enables an interrupt upon completion of queue 2. The interrupt<br />

request is initiated when the conversion is complete for the CCW in<br />

queue 2.<br />

1 = Enable an interrupt after an end-of-conversion for queue 2.<br />

0 = Disable the queue completion interrupt associated with<br />

queue 2.<br />
