Note:
Even parity is used: the parity bit is such that the overall sum of bits in the data byte and the parity bit is an even
number. If a transmission error is detected, the receiving device indicates this by applying a low level on the I/O
channel during the guard time. This tells the transmitting device to retransmit the byte.
Command format
The command sequence is as follows:

I/O

― P1 and P2 are reference bytes, such as a data byte address or password index
― P3 is the number of data bytes transferred during the command. For outgoing transfers (e.g. read commands),
In compliance with ISO 7816-3, the host must send the header consisting of five characters: CLA, INS, P1, P2, P3
― CLA refers to a class of instructions. This byte isn't tested by the device.
― INS is the instruction byte
The device replies with a "procedure byte” normally equal to the INS code received. If a problem occurred, then
the device will respond with a status word pair SW1-SW2, indicating the end of the command.
Data transfer (P3-bytes)
A final SW1-SW2 sequence gives the status of the device after completion of the command. A normal completion
is indicated by SW1-SW2 = $90-$00.

P3 = 0 means that 256-data bytes will be emitted by the card. For incoming commands, P3 = 0 means that no
data bytes will be transferred.
The byte is transmitted with the least significant bit first
For all bytes transmitted by the device or by the host, including header, procedure, status and data bytes, if a
parity error is detected, the receiver requests that byte to be sent again (see character format)
