6.2
Parallel I/O and Pin Control features, depending on package choice, include:
6.3
The MC9S08AC16 Series has a total of 38 parallel I/O pins in seven ports (PTA–PTG). Not all pins are
bonded out in all packages. Consult the pin assignment in
parallel I/O pins. All of these pins are available for general-purpose I/O when they are not used by other
on-chip peripheral systems.
After reset, the shared peripheral functions are disabled so that the pins are controlled by the parallel I/O.
All of the parallel I/O are configured as inputs (PTxDDn = 0). The pin control functions for each pin are
configured as follows: slew rate control enabled (PTxSEn = 1), low drive strength selected (PTxDSn = 0),
and internal pullups disabled (PTxPEn = 0).
The following paragraphs discuss each port and the software controls that determine each pin’s use.
6.3.1
Port A pins are general-purpose I/O pins. Parallel I/O function is controlled by the port A data (PTAD) and
data direction (PTADD) registers which are located in page zero register space. The pin control registers,
pullup enable (PTAPE), slew rate control (PTASE), and drive strength select (PTADS) are located in the
high page registers. Refer to
