Transmit Digits (Bytes)
After conversion, the transmit data is taken out in specified digits. Possible digits depend on the selected conversion type.
Example: D10 stores 010Ch (268)
(1) Binary to ASCII conversion, Transmit digits = 2
(2) BCD to ASCII conversion, Transmit digits = 3
(3) No conversion, Transmit digits = 1
Repeat Cycles
When a data register is designated to repeat, consecutive data registers, as many as the repeat cycles, are used for transmit
data in the same conversion type and transmit digits.
Example:
Data of data registers starting with D10 is converted in BCD to ASCII and is transmitted according to the designated repeat
cycles.
