SECTION 7
INPUT/OUTPUT PORTS
This section describes the general purpose I/O ports on the MC68HC05PL4 and
MC68HC05PL4B MCUs.
In the MC68HC05PL4, 23 bidirectional I/O lines are available, arranged as one
7-bit I/O port (Port A), one 8-bit I/O port (Port B), and one 8-bit I/O port (Port C).
In the MC68HC05PL4B, 22 bidirectional I/O lines are available, arranged as one
6-bit I/O port (Port A), one 8-bit I/O port (Port B), and one 8-bit I/O port (Port C).
NOTE
To avoid generating a glitch on an I/O port pin, data should be written to the I/O
port data register before writing a “1” (for output) to the corresponding data
direction register.
7.1
PARALLEL PORTS
Port A, B, and C are bidirectional ports. Each port pin is controlled by the
corresponding bits in a data direction register and a data register as shown in
Figure 7-1
. The functions of the I/O pins are summarized in
Table 7-1
.
