• Description: 16-Bit Single-Chip Microcontroller
• Manufacturer: INFINEON [Infineon Technologies AG]

so-called General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bitaddressable. When used by a GPR,
any location in the DPRAM is bitaddressable.
1024 bytes (2
Register areas (SFR space and ESFR space). SFRs are wordwide registers which are
used for controlling and monitoring functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the XC166 Family. Therefore, they should
either not be accessed, or written with zeros, to ensure upward compatibility.
In order to meet the needs of designs where more memory is required than is provided
on chip, up to 12 Mbytes (approximately, see
be connected to the microcontroller. The External Bus Interface also provides access to
external peripherals.

Data Sheet
Accesses to the shaded areas generate external bus accesses.
The areas marked with “<“ are slightly smaller than indicated, see column “Notes”.
Not defined register locations return a trap code.
Several pipeline optimizations are not active within the external IO area. This is necessary to control external
peripherals properly.
