3-4
If the XRAM is enabled these instruction will only access the internal XRAM. External memory
cannot be accessed in this case because no external bus cycle will be generated. Therefore, port
0 and 3 can be used as standard I/O, if only the internal XRAM is used.
3.4
General Purpose Registers
The lower 32 locations of the internal RAM are assigned to four banks with eight general purpose
registers (GPRs) each. Only one of these banks may be enabled at a time. Two bits in the program
status word PSW, RS1 and RS0, select the active register bank (see description of the PSW in
chapter 2.1). This allows fast context switching, which is useful when entering subroutines or
interrupt service routines. After reset register bank 0 is selected.
The 8 general purpose registers of the selected register bank may be accessed by register
addressing. With register addressing the instruction opcode indicates which register is to be used.
For indirect addressing R0 and R1 are used as pointer or index register to address internal or
external memory (e.g. MOV @R0).
Reset initializes the stack pointer to location 07H and increments it once to start from location 08H
which is also the first register (R0) of register bank 1. Thus, if one is going to use more than one
register bank, the SP should be initialized to a different location of the RAM which is not used for
data storage.
3.5
Special Function Registers
All registers except the program counter and the four general purpose register banks reside in the
special function register area.
The 34 special function registers (SFR) include pointers and registers that provide an interface
between the CPU and the other on-chip peripherals. There are also 128 directly addressable bits
within the SFR area.
All SFRs are listed in table 3-1 and table 3-2. In table 3-1 they are organized in groups which refer
to the functional blocks of the C511/513. Table 3-2 illustrates the contents of the SFRs, e.g. the bits
of the SFRs.
