6.9 Responses
All responses are sent via the command line CMD. The response transmission always starts with the left bit of the bitstring
corresponding to the response codeword. The code length depends on the response type.
A response always starts with a start bit (always ‘0’), followed by the bit indicating the direction of transmission (card = ‘0’).
A value denoted by ‘x’ in the tables below indicates a variable entry. All responses except for the type R3 (see below) are
protected by a CRC (see Chapter 7.2 for the definition of CRC7). Every command codeword is terminated by the end bit
(always ‘1’).
