Transmit Special Mapped Character 3 (TSPMAP3)
The three TSPMAP registers are used to provide control character escape processing on characters
outside the 00–1f (hex) range. Each of these three registers are scanned to match the character
currently being transmitted; if a match occurs, that character is ‘escaped’ before transmission. If a
zero value is found in any of them, the scan is terminated. (Zero is already covered in the standard
TXACCM.)
