CY545 Command Summary
The following is a list of CY545 commands, including the command letter and argument
structure. Arguments without a suffix should be single byte numeric values up to 255, while
arguments with a "16" suffix may be two byte numbers up to 65535, and arguments with a "24"
suffix may be three byte numbers up to 16777215. Commands are entered as the single upper
case ASCII letter, followed by a space, and the argument value. Multiple arguments may be
separated by a space or comma. The command ends with a carriage return character.
Commands without arguments simply use the command letter, followed directly by the carriage
return.
