The spec says these can be ignored, both reads and writes. The
card ignores optional CRC16 when sending data and likewise host
ignores optional CRC when reading back.
Also both the card and the host ignore all but the first two bits of
the test pattern.

NONE.
Both CMD14 and CMD19 have R1 response.
