2.4.4 Expanded data transfer (XFER)
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 ↔ CPU register
• CPU register ↔ Expanded F register ( IC memory card)
• CPU register ↔ TOSLINE-S20 or TOSLINE-S20LP (here called S20 or S20LP)
• CPU register ↔ EEPROM (D register )
