UM023502-0911 port

port Set/Get GPIO pin state

Syntax

Port reg <op value>

Example 1

port e

Port_E initially 20 now 20

Example 2

port e = 40

Port_E initially 20 now 40

Example 3

port e ^ 60

Port_E initially 40 now 20

The

port console command can be used to manipulate GPIO output pins.

The

port command requires at least one parameter, reg, that specifies

which Z8F2480 GPIO port is being targeted. Valid values of reg are

through

e, which target the GPIO output registers PAOUT through

PEOUT. If the

<op value> parameters are omitted, then the current set-

ting of the GPIO output port is displayed.

The <op value> parameters identify a bit-wise operator to use with the

current value of the port register and the value parameter. Valid

port

operators and their usage are shown in Table 4.

Table 4. port Operator Definitions

Operator (op) Definition

= Assigns value to the target GPIO output port. Equivalent to the “C”

statement: “PxOUT = value;”
