5-34 Memory Card Instructions
Memory Card Instructions all involve the transfer of data to and from the Memory
Card in the memory card drive. The instructions described in this section can
thus only be used if there is a Memory Card in the drive.
Exercise care when transferring a very large number of words, because it can
greatly increase the overall cycle time.
The following flags are used by all of the Memory Card instructions. Refer to
3-6-20 Memory Card Flags for details.
A343 bit(s) Function
00 to 03 Memory Card Type (0:None, 1: RAM, 2: EPROM, 3: EEPROM)

A346 contains the number of words (4-digit BCD) left to transfer from the
Memory Card with FILR(180)/FILW(181).

When the execution condition is OFF, FILR(180) is not executed. When the ex-
ecution condition is ON, FILR(180) reads N words of data from the memory card
data file ( filename .IOM) specified in C+1 to C+4, and outputs the data to the des-
ignated memory area beginning at D.
The name of the file from which the data is read is specified by eight ASCII char-
acters in C+1 to C+4. Data will be read from the word indicated in C+5 if C bit 04
(the Offset Enable Bit) is ON. The following table shows the function of bits in the
control words.
Word Bit(s) Function Bit(s) Function
C 04 Offset Enable Bit (ON:
enabled, OFF: disabled)
Other Turn OFF.
C+1 08 to 15 First character in name 00 to 07 Second character in name
C+2 08 to 15 Third character in name 00 to 07 Fourth character in file
C+3 08 to 15 Fifth character in name 00 to 07 Sixth character in file
C+4 08 to 15
Seventh character in name
00 to 07 Eighth character in file
C+5 00 to 15 Offset from beginning of file (0000 to 9999, BCD)
If the filename is less than 8 characters long, enter #20 for the bytes that aren’t
required. It is not necessary to input the filename extension “.IOM.”
