Figure 22. Command byte format for Write SC1_CFG0 command
A general call followed by the value 06h has the same effect as a Reset command.
Initialize all the logic and the TWI interface as after a power-up or power-fail reset. If the
interface is activated, an emergency de-activation sequence is also performed. This is a
one-byte command.
Configure the device according to the last six bits in the SC1_CFG0 register and to the fol-
lowing four bytes in SC1_CFG1, SC1_CFG2, SC1_CFG3 then SC1_CFG4 registers. This is
a five bytes command.
Program the 16-bit automatic reset transition timer with the following two bytes. This is a
three bytes command.
Program the interface byte. This is a one-byte command. The MSB of the command byte is
fixed at 0.
IO_SELECT, INTERFACE_B, ITDIS:
Configuration of parameters for smart card interfaces.
Configuration of smart card interface 2.
Configuration of SIM/SAM interface 3.
Configuration of SIM/SAM interface 4.
