Parity flag, affected by hardware to indicate odd / even number of “one” bits in the
Accumulator, i.e. even parity.
Table 9: PSW bit functions
Stack Pointer ( SP ): The stack pointer is a 1-byte register initialized to 0x07 after reset. This register is incremented before
PUSH and CALL instructions, causing the stack to begin at location 0x08.
Data Pointer: The data pointer ( DPTR ) is 2 bytes wide. The lower part is DPL , and the highest is DPH . It can be loaded as a 2-
byte register (MOV DPTR ,#data16) or as two registers (e.g. MOV DPL ,#data8). It is generally used to access external code or
data space (e.g. MOVC A,@A+ DPTR or MOVX A,@ DPTR respectively).
Program Counter: The program counter ( PC ) is 2 bytes wide initialized to 0x0000 after reset. This register is incremented
during the fetching operation code or when operating on data from program memory.
