Control register 2 (QACR2) is the mode control register for the operation
of queue 2. Software specifies the queue operating mode of queue 2
and may enable a completion and/or a pause interrupt. Most of the bits
are typically written once when the software initializes the QADC and not
changed afterward.
Stop mode resets the register ($007f)
Read: Anytime
Write: Anytime except stop mode
CIE2 — Queue 2 Completion Software Interrupt Enable Bit
CIE2 enables an interrupt upon completion of queue 2. The interrupt
request is initiated when the conversion is complete for the CCW in
queue 2.
