VEDA HCT User Manual “Set Up Character Strings” has two optional attributes “Use UNICODE” and “Swap high and low bytes”. When “Use UNICODE” is checked, it means the character string written to registers is coded by UNICODE. The string is normally displayed only in “UNICODE”. If “Swap high and low bytes” is checked, the high and low bytes in the character string will be exchanged before written to the word register. Set Up Figures By Bit This function has two modes, “Add” and “Subtract”. By this function, each bit of the value can be added or subtracted. This function has an attribute “Date type”. It can be “16-bit Unsigned” or “32-bit unsigned number”.
In other words, only unsigned single word and unsigned double word can use this function. If the data type is “16-bit unsigned number”, the value range is 0~65535. So the parameter of this function “Digit bit” can be 1~5. That means the number length is 1~5. “1” means units digit, “2” means tens digit, “3” means hundreds digit, “4” means thousands digit, and “5” means ten thousands digit. For example, if the “Digit bit” is 3 and the “Mode” is “Add”, it means the hundreds digit is operated for adding. If the hundreds digit of a register is 6 and when this component is pressed down, the hundreds bit will change into 7, and then into 8 if it is pressed 104
