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.
It also provides indicators to monitor the output status for the ports that have been set for general-purpose output.
Port data control window
Click on a control window select tab to select the port group (P0x, P1x, P2x, P3x) you want to operate or
display.
Port data button
Simultaneous input ports select check box Simultaneous input button
Port data control window (P0x port)
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.
Setting the port input status
Select either High or Low port data button. This determines the current port input level.
P00 input = High P01 input = Low
