STANDARD DIGITAL PORTS
After reset all ports are usually Inputs. please note that some options my change this (See Chapter CONFIG
REGISTER). A DEACT instruction will make the port an INPUT, a write instruction will make the port an
OUTPUT (ecept the ports which are read or write only)
PORT READ/WRITE
Prior to any operation of ports, a port has to be defined (see Chapter DECLARATIONS and DEFINITIONS)
Reading a Bitport returns a boolean value which is ON (true) for a port that is logic high level and OFF for a
port that is logic low level. Bitports may also accessed by read/write with the numerical value 0(false) and -
1(true) instead of ON and OFF
MyBitPort = -1would also work to set the port to ON but is not recommended. See Chapter DATA TYPES
also.

IF MyBitPort1=OFF THEN GOTO X
IF MyBitPort1=ON THEN GOTO X
Example for request Bitport input status
Example for request Byteport input
status
IF MyBytePort1=123 THEN GOTO X
MyBitPort1=OFF
MyBitPort1=ON
Example for setting a Bitport output
MyBytePort1=123
Example for setting a Byteport output
TOG
TOG (toggle) is an instruction which changes the current port status to its opposite. I.e a port becomes ON if
it was previously OFF and reverse. Prior to use TOG, the affected port has to be switched to OUTPUT (e.g
MyPort=OFF) otherwise TOG will not work. TOG is not working with Byteports and Extended Ports
Syntax: TOG(bitport)

PULSE
PULSE is an instruction which changes the current port status for 5us and then returns to its previous status
I.e a port becomes ON for a very short time if it was previously OFF and reverse. Prior to use PULSE, the
affected port has to be switched to OUTPUT (e.g MyPort=OFF) otherwise PULSE will not work. PULSE is
not working with Byteports and Extended Ports

DEACT
DEACT will cause an output port to return to operate as input
