Command error summary. If bit 7 is 1 then the remaining bit
indicate communications errors as follows:
Bit 6: vertical parity error.
Bit 5: overrun error.
Bit 4: framing error.
Bit 3: longitudinal parity error.
Bit 2: reserved, set to 0.
Bit 1: buffer overflow.
Bit 0: not used.
If bit 7 is 0 the remaining bits contain a command specific
response code in the range 0 to 127. Some common
response codes are:
0: Success – command completed successfully.
32: Busy – the device is performing a function that cannot
be interrupted by this command.
64: Command not implemented – the device does not
support the command.
