73S1217F Data Sheet  
DS_1217F_002  
1.5 Special Function Registers (SFRs)  
The 1217 utilizes numerous SFRs to communicate with the many 1217 peripherals. This results in the  
need for more SFR locations outside the direct address IRAM space (0x80 to 0xFF). While some  
peripherals are mapped to unused IRAM SFR locations, additional SFRs for the USB, smart card and  
other peripheral functions are mapped to the top of the XRAM data space (0xFC00 to 0xFFFF).  
1.5.1 Internal Data Special Function Registers (SFRs)  
The Special Function Registers map is shown in Table 6.

Only a few addresses are used, the others are not implemented. SFRs specific to the 73S1217F are  
shown in bold print (gray background). Any read access to unimplemented addresses will return  
undefined data, while most write access will have no effect. However, a few locations are reserved and  
not user configurable in the 73S1217F. Writes to the unused SFR locations can affect the operation  
of the core and therefore must not be written to. This applies to all the SFR areas in both the  
IRAM and XRAM spaces. In addition, all unused bit locations within valid SFR registers must be  
left in their default (power on default) states.
