7. Setups and Status Information
7.1 Introduction
The bytes of the setup table can be written to or read from individually. The setup table and the corresponding Set
and Get commands are listed in Table 7-1. Note that there is a discontinuity in the Set and Get commands; 0xAF
and 0xEF are not implemented.
