4.2.1 Register Settings
Table 4.17 lists Registers with Write-Only Bits and registers whose function differs between reading and
writing. Set these registers with immediate values. When establishing the next value by altering the
existing value, write the existing value to the RAM as well as to the register. Transfer the next value to
the register after making changes in the RAM.
