QADC Control Register 1 (QACR1)

QACR1 is the mode control register for queue 1. This register governs queue operating mode and the use
of completion and/or pause interrupts. Typically, these bits are written once when the QADC is initialized
and are not changed thereafter.

Stop mode resets this register.
