Notes on SFRs
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. Do not use read-modify-write instructions. 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.
