Section 3 Command Descriptions
3.5
Configure Cn
Ports 1 thru 5 are configured as inputs or outputs with the
Configure
command.
Each port is eight bits wide. At power-on, all ports are initialized as inputs. The
Configure
command is usually the first command to be sent after power on. All ports
programmed as outputs will be set to a logic zero after receiving the
Configure
command. The actual output level is dependent on the
Invert
command (
I16
)
.
