Chapter 15
Parallel Port (General-Purpose I/O)
This chapter describes the operation and programming model of the parallel port pin
assignment, direction-control, and data registers. It includes a code example for setting up
the parallel port.
15.1 Parallel Port Operation
The MCF5407 parallel port module has 16 signals, which are programmed as follows:
The operations of the PAR, PADDR, and PADAT are described in the following sections.
15.1.1 Pin Assignment Register (PAR)
The pin assignment register (PAR), which is part of the system integration module (SIM),
defines how each PAR bit determines each pin function, as shown in Figure 15-1.
If PP[9:8]/A[25:24] are unavailable because A[25:0] are needed for external addressing,
PP[15:10]/A[31:26] can be configured as general-purpose I/O. Table 15-1 summarizes
MCF5407 parallel port pins, described in detail in Chapter 17, “Signal Descriptions.”
Address
• The pin assignment register (PAR) selects the function of the 16 multiplexed pins.
• Port A data direction register (PADDR) determines whether pins configured as
• The Port A data register (PADAT) shows the status of the parallel port signals.
Reset Determined by driving D4/ADDR_CONFIG with a 1 or 0 when RSTI negates. The system is configured as
Field PAR15 PAR14 PAR13 PAR12 PAR11 PAR10 PAR9 PAR8 PAR7 PAR6
R/W
parallel port signals are inputs or outputs.
PP[15:0] if D4 is low; otherwise alternate pin functions selected by PAR[n] = 1 are used.
