Register (FSR). In addition, Special Purpose Registers are used to control the
I/O port configuration and prescaler PRESCALEs.
The General Purpose Registers are used for data and control information
under command of the instructions.
FLAGS Register
This register contains the arithmetic FLAGS of the ALU, the RESET FLAG.
The FLAGS Register can be the destination for any instruction, as with any
other register. If the FLAGS Register is the destination for an instruction that
affects the Z, DC or C bits, then the write to these three bits is disabled. These
bits are set or cleared according to the device logic. Furthermore, the TO and
PD bits are not writable. Therefore, the result of an instruction with the FLAGS
Register as destination may be different than intended.
For example, CLR FLAGS will clear the upper three bits and set the Z bit. This
leaves the FLAGS Register as 000u u1uu (where u = unchanged).
It is recommended, therefore, that only SETB, CLRB and LD instructions be
used to alter the FLAGS Register because these instructions do not affect the Z,
DC or C bits from the FLAGS Register. For other instructions which do affect
FLAGS Bits, see the Instruction Set Summary.
