1.5 Special Function Registers (SFRs)
Hex\Bin
73S1210F Data Sheet
The 73S1210F utilizes numerous SFRs to communicate with the 73S1210Fs many 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 smart card and
other peripheral functions are mapped to the top of the XRAM data space (0xFC00 to 0xFFFF).
1.5.1
A map of the Special Function Registers is shown in Table 6.
Only a few addresses are used, the others are not implemented. SFRs specific to the 73S1210F 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 73S1210F. 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.
