I/O ports
81/127
19.3
MCU I/O mode
In the MCU I/O mode, the MCU uses the PSD ports to expand its own I/O ports. By setting
up the CSIOP space, the ports on the PSD are mapped into the MCU address space. The
addresses of the ports are listed in Table 6.
A port pin can be put into MCU I/O mode by writing a 0 to the corresponding bit in the
Control register (for Ports E, F and G). The MCU I/O direction may be changed by writing to
the corresponding bit in the Direction register, or by the output enable product term. See
Section 19.2: Port operating modes. When the pin is configured as an output, the content of
the Data Out register drives the pin. When configured as an input, the MCU can read the
port input through the Data In buffer. See Figure 31.
Ports A, B and C do not have Control registers, and are in MCU I/O mode by default. They
can be used for PLD I/O if they are specified in PSDsoft.
19.4
PLD I/O mode
The PLD I/O mode uses a port as an input to the CPLD’s input macrocells (IMC), and/or as
an output from the CPLD’s output macrocells (OMC). The output can be tri-stated with a
control signal.
This output enable control signal can be defined by a product term from the PLD, or by
resetting the corresponding bit in the Direction register to 0. The corresponding bit in the
Direction register must not be set to 1 if the pin is defined for a PLD input signal in PSDsoft.
The PLD I/O mode is specified in PSDsoft by declaring the port pins, and then specifying an
equation in PSDsoft.
19.5
Address Out mode
For MCUs with a multiplexed address/data bus, Address Out mode can be used to drive
latched addresses onto the port pins. These port pins can, in turn, drive external devices.
Either the output enable or the corresponding bits of both the Direction register and Control
register must be set to a 1 for pins to use Address Out mode. This must be done by the
MCU at run-time. See Table 43 for the address output pin assignments on Ports E, F and G
for various MCUs.
Note: Do not drive address signals with Address Out mode to an external memory device if
it is intended for the MCU to Boot from the external device. The MCU must first Boot from
PSD memory so the Direction and Control register bits can be set.
