INPUT/OUTPUT PORTS
MC68HC05J5A
7-2
REV 2.1
Each Port A pin is controlled by the corresponding bits in a data direction register,
a data register and a pulldown/up register. The Port A Data Register is located at
address $0000. The Port A Data Direction Register (DDRA) is located at address
$0004. The Port A Pulldown/up Register (PDURA) is located at address $0010.
Reset operation will clear the DDRA and the PDURA. The Port A Data Register is
unaffected by reset.
Figure 7-2. Port A I/O Circuitry
7.2.1 Port A Data Register
Each Port A I/O pin has a corresponding bit in the Port A Data Register. When a
Port A pin is programmed as output, the corresponding data register bit deter-
mines the logic state of that pin. When a Port A pin is programmed as input, any
read from the Port A Data Register will return the logic state of the corresponding
I/O pin. The Port A data register is unaffected by reset.
7.2.2 Port A Data Direction Register
Each Port A I/O pin may be programmed as input by clearing the corresponding
bit in the DDRA, or programmed as output by setting the corresponding bit in the
DDRA. The DDRA can be accessed at address $0004. The DDRA is cleared by
reset.
If congured as output pins, PA6 and PA7 have slow output falling-edge transition
feature. The slow transition feature is controlled by the SLOWE bit of DDRB.
SLOWE bit, if set and if the pin is congured as an output pin, enables the slow
falling-edge output transition feature of all four I/O lines, PA6, PA7, PB1, and PB2.
