The MC68HC912DT128A incorporates eleven ports which are used to
control and access the various device subsystems. When not used for
these purposes, port pins may be used for general-purpose I/O. In
addition to the pins described below, each port consists of a data register
which can be read and written at any time, and, with the exception of port
AD0, port AD1, PE[1:0], RxCAN and TxCAN, a data direction register
which controls the direction of each pin. After reset all general purpose
I/O pins are configured as input.
Port A pins are used for address and data in expanded modes. When
this port is not used for external access such as in single-chip mode,
these pins can be used as general purpose I/O. The port data register is
not in the address map during expanded and peripheral mode operation.
When it is in the map, port A can be read or written at anytime.
Register DDRA determines whether each port A pin is an input or output.
DDRA is not in the address map during expanded and peripheral mode
operation. Setting a bit in DDRA makes the corresponding bit in port A
an output; clearing a bit in DDRA makes the corresponding bit in port A
an input. The default reset state of DDRA is all zeroes.
When the PUPA bit in the PUCR register is set, all port A input pins are
pulled-up internally by an active pull-up device. PUCR is not in the
address map in peripheral mode.
