Parity flag, affected by hardware to indicate odd / even number of “one”
bits in the Accumulator, i.e. even parity.
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. Note: The program counter is not mapped to the SFR area.
Port Registers: The I/O ports are controlled by Special Function Registers USR70, and USR8. The
contents of the SFR can be observed on corresponding pins on the chip. Writing a 1 to any of the ports
(see Table 11) causes the corresponding pin to be at high level (3.3V), and writing a 0 causes the
corresponding pin to be held at low level (GND). The data direction registers UDIR70, and UDIR8 define
individual pins as input or output pins (see the User (USR) Ports section for details).
