Data Sheet
22
This section summarizes all registers, which are implemented in the C161U and explains
the description format which is used in the chapters describing the function and layout of
the SFRs.
For easy reference the registers are ordered according to two different keys (except for
GPRs):
• Ordered by address, to check which register a given address references,
• Ordered by register name, to find the location of a specific register.
22.1
In the respective chapters the function and the layout of the SFRs is described in a
specific format which provides a number of details about the described special function
register. The example below shows how to interpret these details.
A word register looks like this:
REG_NAME (A16
A byte register looks like this:
REG_NAME (A16
