20-8 ASCII Instructions
Addressing Modes and File Types can be used as shown below:
Instruction Operation
When Clear Receive Buffer and Clear Transmit Buffer are both set to Yes,
all Receive and Transmit instructions (ARL, ARD, AWA, and AWT) are
removed from the ASCII queue.
When instructions are removed from the ASCII queue, the following bits
are set: ER = 1, RN = 0, EU = 0, and ERR = 0x0E.
AIC - ASCII Integer to
String
Instruction Type: output
The AIC instruction converts an integer or long word value (source) to an
ASCII string (destination). The source can be a constant or an address.
The source data range is from -2,147,483,648 to 2,147,483,647.
