wise fashion for reading and programming, and in
a byte-wise fashion for internal erasing.
The device recognises three commands issued
via the RST and CLK pins (as described in the full
data sheet):
– RESET: to reset the internal address register to
00d
– READ: to increment the internal address regis-
ter, and read the data bit at that address
– PROG: to program the bit at the current ad-
dress.
The device offers two distinct configurations:
– ISSUER: for the card manufacturer, allowing
special data to be written to the chip, during ini-
tialisation
– USER: for the end user of the card, restricting
access to the chip.
Before delivery, from ST to the card issuer, the de-
vice is placed in the ISSUER configuration. This
operation is performed by blowing the “test fuse”.
