10.11.4 Simulating i/O Ports

The [ES-Sim] window allows control of the input status for the ports that have been set for general-purpose input.

The ES-Sim17 obtains the information, such as selected I/O port functions and I/O directions, from the
emulation memory in the PC to determine the port configuration to be displayed in the port data control
window.
The port data buttons and simultaneous input ports select check boxes for the ports configured as general-
purpose input becomes effective and are used to set input levels. When you change the input level in the
window, the ES-Sim17 updates the input data register in the emulation memory through the debugger.
The port data buttons and simultaneous input ports select check boxes for the ports configured as a general-
purpose output are grayed out to disable operations. However, the port data buttons indicate the current output
status. When the output data register for the port configured as a general-purpose output is altered by the
program, its status is reflected to the port data button.
The port data buttons and simultaneous input ports select check boxes for the ports configured to an internal
peripheral input/output are not displayed.
The port data buttons and simultaneous input ports select check boxes for the ports that do not exist in the target
model are not displayed.
