2 / 2 page ST1305B 2/2 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”. Figure 2.
