About the X5 XMC Modules
Function Type Description
DioPortData() Property Broadside Read/Write to low-order 32-bits of
DIO.
Typical use of the digital IO port involves first configuring the port using the Config() operator. This sets the byte direction and
the clock mode. The port is then ready for read/write configurations to each port. For instance:
// Open the module
Innovative::X5_400M Module;
Module.Target(0);
Module.Open();
// All bits input
Module.Config(0x0);
// Read the state of the port
volatile short x = Module.DioPortData();
// All bits output
Module.Config(0x3);
// Toggle the state of all output bits
while (1)
Module.DioPortData(~Module.DioPortData());
Hardware Implementation
Digital I/O port activity is controlled by the digital I/O configuration control and data register. Port direction is controlled by
the configuration control register.
