Parallel Input/Output Control
This section explains software controls related to parallel input/output (I/O) and pin control. The
MC9RS08KA2 Series has one parallel I/O port, which includes two I/O pins in the 6-pin package or four
I/O pins in the 8-pin packages, one output-only pin, and one input-only pin. See Chapter 2, “Pins and
Connections,” for more information about pin assignments and external hardware considerations for these
pins.
All of these I/O pins are shared with on-chip peripheral functions as shown in Table 2-1. The peripheral
modules have priority over the I/Os so that when a peripheral is enabled, the I/O functions associated with
the shared pins are disabled. After reset, the shared peripheral functions are disabled so that the pins are
controlled by the I/O. All of the I/Os are configured as inputs (PTADDn = 0) with pullup/pulldown devices
disabled (PTAPEn = 0), except for output-only pin PTA3, which defaults to the BKGD/MS function.
Reading and writing of parallel I/Os is performed through the port data registers. The direction, either input
or output, is controlled through the port data direction registers. The parallel I/O port function for an
individual pin is illustrated in the block diagram shown in Figure 6-1.
Figure 6-1. Parallel I/O Block Diagram
The data direction control bit (PTADDn) determines whether the output buffer for the associated pin is
enabled, and also controls the source for port data register reads. The input buffer for the associated pin is
always enabled unless the pin is enabled as an analog function or is an output-only pin.
