When FILR(180) is executed, the CPU first checks whether the ER Flag
(A50003) is ON, then processes the data transfer and following instructions in
parallel, so check the Memory Card Instruction Flag (A34313) to verify that
FILR(180) has been completed correctly.
The number of words to transfer (N) must be BCD.
If bit 04 of C is ON, C+5 must be BCD.
If N exceeds the number of words remaining in the file, only the words in the file
will be transferred and no error will occur.
Write the execution condition for FLSP(183) so that the instruction will not be
executed if the Memory Card Instruction Flag (A34313) is ON (when another
memory card instruction is being executed).
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): N is not BCD.
Bit 04 of C is ON, but the content C+5 is not BCD.
Content of *DM word is not BCD when set for BCD.
A Memory Card is not mounted.
A34310: The file not read if the offset in C+5 is larger than the file.
A34311: The specified file doesn’t exist on the card.
In the following example, 20 words, beginning from the 17
th
word of the file, are
transferred from memory card data file “ABCD” to D01000 to D01019.
Here, the content of CIO 0300 would be 0020 (BCD) to indicate reading 20
words. The contents of the control words would be as follows:
Word Leftmost

Rightmost
