Section 2.12, p. 8
Lowercase 'E'. Returns the error byte for a selected key
defined by the 's' command. A 4-bit pattern is returned:
Refer also to Section 2.10.
F, Bit 0 is set if it failed to calibrate properly during a forced
recalibration. The sensor will automatically make 5 sequential
attempts at recalibration before setting this flag.
R, Bit 1 is set if the key is in the process of a full
recalibration. When set, bits 2 and 3 are immediately cleared.
H, Bit 2 when set indicates either:
L, Bit 3 when set indicates either:
Bits 2 and 3, if set via drift compensation, would indicate that
the key should be recalibrated by the host. If H and L bits
appear immediately after a full recalibration, it means that the
key is probably defective.
Section 2.12, p. 8
Uppercase 'E'. Returns general error codes for a range of
keys defined by scope. Returns either 1 or 8 bytes depending
on whether a single key, row, column, or entire matrix are
selected.
The bitfields for a single key are the same as for 'e' above.
The bitfields for a single row (X) are:
The bitfields for a single column (Y) are:

The bitfields for a global response are:
Byte 1 is the first returned byte in the sequence.
In all the above examples a '1' in a bit position indicates that
there is some type of error associated with the key. The use
of the 'e' command (or 'E' with scope set to a specific key) will
specify the nature of the error.
Section 2.12, p. 8
Lowercase 'K'. Returns a byte that indicates which if any key
has been touched. The byte is structured as follows:
Bits are used as follows:
If a reported key drops out while other keys are active, 'k' will
report one of the other active keys, but there is no rule for
which of the next keys gets reported in k0..k5.
If the byte returned has a value of 255 (0xFF), then no key
has been detected.
