UM0404 Register set
26 Register set
This section summarizes all registers implemented in the ST10F276, and explains the
description format used in the sections describing the function and layout of the SFRs.
For easy reference the registers (except for GPRs) are ordered in two ways:
•
Ordered by register name, to find the location of a specific register.
•
Ordered by address, to check which register a given address references.
26.1 Register description format
Along the document, the function and the layout of the different registers is described in a
specific format. The examples below explain this format.
A word register looks like this:
REG_NAME (A16h / A8h) SFR/ESFR/XBUS Reset Value: ****h
A byte register looks like this:
REG_NAME (A16h / A8h) SFR/ESFR/XBUS Reset Value: - - **h

SFR / ESFR/XBUS Register space (SFR, ESFR or XBUS Register)
(* *) * * Register contents after reset
0/1 : defined
x : undefined (undefined (’ x ’) after Power-On)
U : unchanged
hw bit bits that are set/cleared by hardware are written in bold
- bits that are not implemented or reserved: never write to these bits
