port
Display or change the contents of an 8-bit I/O port.
Syntax
[result =] [[px]] port(io-addr) [= expr]
Where:
|
result |
specifies an debug variable of type ord 1 to which the function return value is assigned. If result is not specified, the return value is displayed on the next line of the screen. |
|
[px] |
is the viewpoint override, including punctuation ( [ ] ), specifying that the viewpoint is temporarily set to processor x of the boundary scan chain. The processor can be specified as px (where x is the processor ID), or an alias you have defined for a given processor ID. ALL cannot be used as a viewpoint override. |
|
io-addr |
specifies a 16-bit address in the processor I/O space. The available io-addr range is 0 to 0ffffh. The use of parentheses is optional. |
|
expr |
specifies a 8-bit number or expression. Using this option writes the data to the specified I/O port. |
Discussion
Use the port command to read from and write to the specified I/O port with the specified 8-bit data. You can access up to 64K 8-bit ports.
Example 1
To display and change the contents of the I/O port at address 88h:
Command input:
port 88h
Result:
0088H FFH "."
Command input:
port 88h = 0abh
port 88h
Result:
ABH "."
Example 2
To assign one port value to another port:
Command input:
port 90h = port 88h
Example 3
To create a debug variable named portvar and assign a port value to it:
Command input:
define ord1 portvar
portvar = port 90h
portvar
Result:
FFH
