There are the SFRs with write-only bits which can only be written to. Set these registers with undefined
values. When establishing the next value by altering the present value, write the present value to the RAM
as well as to the register. Transfer the next value to the register after making changes in the RAM.
Table 23.1 lists Registers with Write-only Bits.
