Introduction

This section summarizes all registers implemented in the ST10F276E and explains the

description format used in the chapters to describe the function and layout of the SFRs. For

easy reference, the registers (except for GPRs) are sorted in two ways:

–

Sorted by address, to check which register is referenced by a given address.

–

Sorted by register name, to find the location of a specific register.

22.2

Throughout the document, the function and the layout of the different registers is described

in a specific format. The example below explains this format.

A word register is displayed as:

A byte register is displayed as:
