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 a
through e , which target the GPIO output registers PAOUT through
PEOUT. If the parameters are omitted, then the current set-
ting of the GPIO output port is displayed.
The 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;”
