Functional Description

Data Sheet

V1.2, 2007-03

can consist of up to 16 word wide (R0 to R15) and/or byte wide (RL0, RH0, …, RL7, RH7)

so-called General Purpose Registers (GPRs).

The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR,

any location in the DPRAM is bit addressable.

1024 bytes (2

× 512 bytes) of the address space are reserved for the Special Function

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.
