GMS90 Series  
HYUNDAI MicroElectronics  
SPECIAL FUNCTION REGISTERS  
All registers, except the program counter and the four general purpose register banks, reside in the special func-  
tion register area.  
The 28 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 1, Table 1, and Table 3.  
In Table 1 they are organized in numeric order of their addresses. In Table 2 they are organized in groups which  
refer to the functional blocks of the GMS90 series. Table 3 illustrates the contents of the SFRs.
