Data Sheet
5.4
The peripherals can be grouped into peripherals which are connected to the PD-bus
(GPT, ASC, SSC) and peripherals which are connected to the XBUS (see Figure 3-1).
While the PD-bus peripherals are configured by the SFR or ESFR resprectively, the X-
bus peripherals (e.g. USB, I2C, IOM handler) are configured by XBUS SFR’S which are
located in the XPER area as described in Figure 5-2.

Code accesses are always made on even byte addresses. The highest possible code
storage location in the internal DP-RAM is either 00’FDFE
or 00’FDFC
instruction (unconditional), because sequential boundary crossing from internal RAM to
the SFR area is not supported and causes erroneous results.
Any word and byte data in the internal DP-RAM can be accessed via indirect or long
16-bit addressing modes, if the selected DPP register points to data page 3.
