FUN 236
XFER
Expanded data transfer
Expression
Input − [ A XFER B → C ]− Output
Function
When the input is ON, data block transfer is performed between the source which is indirectly designated by A and A+1 and the destination which is indirectly designated by C and C+1. The transfer size (number of words) is designated by B.
The transfer size is 1 to 256 words. (except for writing into EEPROM) Data transfer between the following objects are available.
• | CPU register (RW or D) | ↔ | EEPROM (D register) |
• | CPU register (RW or D) | ↔ | T1S |
Execution condition
