4.10. Responses

All responses are sent via the CMD line. The response transmission always starts with the MSB. The response

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. Every response is terminated by the end bit (always ‘1’).
