For detailed diagnostic information, the serial data communication can be enabled.
For the inverted slope angular value in the DATA nibbles D3 to D5 the order of nibbles is
also reversed: LSN and MSN.
When a diagnostic condition occurs in A.1 mode, the DATA nibbles D0 to D2 are all set
to Fh and DATA nibbles D3 to D5 are all set to 0h. In H.1 mode, the data value of nibbles
D0 to D2 is set to 4090 and DATA nibbles D3 to D5 are inverted to diagnostic value 5.
