Control register 1 (QACR1) is the mode control register for the operation
of queue 1. The applications software defines the queue operating mode
for the queue and may enable a completion and/or 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 ($0000)
Read: Anytime
Write: Anytime except stop mode
CIE1 — Queue 1 Completion Interrupt Enable Bit
CIE1 enables an interrupt upon completion of queue 1. The interrupt
request is initiated when the conversion is complete for the CCW in
queue 1.
