RDBIT/PUTBIT
The RDBIT command increments the internal address
counter on the leading edge of the SCK pulse and
reads the resulting bit in EEPROM. This SDIO line is
updated on the falling edge of the SCK pulse. If the new
address is in the UKEY0 area, the SDIO line will be
tri-stated immediately in preparation of transport code
entry, even if the device is in user mode. Figure 3-2
shows two consecutive RDBIT commands.
The PUTBIT command mirrors a RDBIT command, but
data is transmitted to the chip instead of transmitting
data from the chip. It also increments the internal
address counter. PUTBIT is used to enter the transport
code in issuer mode and the challenge bits, during
signature computation. Figure 3-3 shows data entry,
typically during transport code entry.
