● Since the amount of data to be converted is specified in bytes, it is also possible to convert
only the low byte of one word data.
● If the data size to be converted is an odd number, bits of the final data of the conversion
result are padded with '0'.
1. Bits 0 to 3 are padded with '0'. (In the forward direction)
2. Bits 0 to 7 are padded with '0'. (In the reverse direction)
■
Setting the conversion data amount and conversion direction [S2]
Specify a 4-digit BCD (H constant) according to the following format.
Size of data to be converted
1 to 16 words
Conversion direction
0: Forward direction
1: Reverse direction
