QADC64E Enhanced Mode Operation
Each port A or B signal is configured as an input or output by programming the port data direction register
(DDRQA or DDRQB). The digital input signal states are read by the software in the upper half of the port
data register when the port data direction register specifies that the signals are inputs. The digital data in
the port data register is driven onto the port A or B signals when the corresponding bit in the port data
direction register specifies output. Refer to
Since the outputs are configured as push-pull drivers, external pull-up provisions are not necessary when
the output is used to drive another integrated circuit.
14.6.2
The QADC64E uses two external trigger signals (ETRIG[2:1]). Each of the two input external trigger
signals is associated with one of the scan queues, queue 1 or queue 2 The assignment of ETRIG[2:1] to a
queue is made in the QACR0 register by the TRG bit. When TRG=0, ETRIG1 triggers queue 1 and
ETRIG2 triggers queue 2. When TRG=1, ETRIG1 triggers queue 2 and ETRIG2 triggers queue 1.
