REGISTER SUMMARY
MOTOROLA
B-3
B.2.4 Port A/B Data Register
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 a bidirectional 8-bit input/output
port that may be used for general-purpose digital input signals or digital open drain out-
put signals. Port A can also be used for analog inputs (AN[59:52]), external trigger in-
puts (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 input only 8-bit digital port
that may be used for general-purpose digital input signals. Port B can also be used for
nonmultiplexed (AN[51:48])/AN[3:0]) and multiplexed (ANz, ANy, ANx, ANw) analog
inputs. Read operations on the reserved bits return zeros, and writes have no effect.
B.2.5 Port Data Direction Register
The port data direction register (DDRQA) is associated with the port A digital I/O pins.
The bidirectional pins have somewhat higher leakage and capacitance specifications.
Refer to
APPENDIX A ELECTRICAL CHARACTERISTICS
for more information. Any
bit in this register set to one configures the corresponding pin as an output. Any bit in
this register cleared to zero configures the corresponding pin as an input. The software
is responsible for ensuring that DDR bits are not set to one on pins used for analog
inputs. When the DDR bit is set to one and the pin is selected for analog conversion,
the voltage sampled is that of the output digital driver as influenced by the load.
NOTE
Caution should be exercised when mixing digital and analog inputs.
This should be isolated as much as possible. Rise and fall times
should be as large as possible.
