Queued Analog-to-Digital Converter (QADC)
28.6.5
This subsection describes the QADC control registers.
28.6.5.1 QADC Control Register 0 (QACR0)
QACR0 establishes the QADC sampling clock (QCLK) with prescaler parameter fields and defines
whether external multiplexing is enabled. Typically, these bits are written once when the QADC is
initialized and not changed thereafter. The bits in this register are read anytime, write anytime (except
during stop mode).

Externally multiplexed mode. Configures the QADC for operation in externally
multiplexed mode, which affects the interpretation of the channel numbers and forces
the MA[1:0] signals to be outputs.
1 Externally multiplexed, up to 18 possible channels
0 Internally multiplexed, up to 8 possible channels
Reserved, should be cleared.
Trigger assignment. Determines the queue assignment of the ETRIG[2:1] signals.
1 ETRIG1 triggers queue 2; ETRIG2 triggers queue 1.
0 ETRIG1 triggers queue 1; ETRIG2 triggers queue 2.
