High−level Instructions
3 − 44
Description
S2 words of data stored in the CPU starting from S1 are transferred into the expansion memory area in the IC
card specified by D.
The F13 (ICWT)/P13 (PICWT) instruction can be executed only in the expansion memory area of an
SRAM−type IC card.
Precautions during programming
The values available for D vary depending on the size of expansion memory area in the IC card.

Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− No IC card is installed in the CPU.
− The IC card access enable switch is set to off (disabled).
− Write protect is in effect on the card side.
− The card is a FLASH−EEPROM type.
− No expansion memory area is found on the IC card.
− The area specified by S2 exceeds the limit of the expansion memory area
of IC card.
− The area is exceeded when blocks specified by D and subsequent
parameters are transferred.
