MULTIPLEXED ADDRESS OUTPUTS:
Only the upper six bits of IVB[7:0] can be initialized. During interrupt arbitration, the
vector provided by the QADC is made up of IVB[7:2], plus two low-order bits that
identify one of the four QADC interrupt sources. Once IVB is written, the two low-order
bits always read as zeros.
QADC ports A and B are accessed through two 8-bit port data registers (PORTQA and
PORTQB). Port A pins are referred to as PQA[7:0] when used as an 8-bit input/output
port. Port A can also be used for analog inputs (AN[59:52]), external trigger inputs
(ETRIG[2:1]), and external multiplexer address outputs (MA[2:0]).
Port B pins are referred to as PQB[7:0] when used as an 8-bit input only port. Port B
can also be used for non-multiplexed (AN[51:48])/AN[3:0]) and multiplexed (ANz, ANy,
ANx, ANw) analog inputs.
Bits in this register control the direction of the port QA pin drivers when pins are con-
figured for I/O. Setting a bit configures the corresponding pin as an output; clearing a
bit configures the corresponding pin as an input. This register can be read or written
at any time.
