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.
