Preliminary User’s Manual U17566EE1V2UM00
Preface
Readers
This manual is intended for users who want to understand the functions of the
concerned microcontrollers.
Purpose
This manual presents the hardware manual for the concerned microcontrollers.
Organization
This system specification describes the following sections:
• Pin function
• CPU function
• Internal peripheral function
Module instances
These microcontrollers may contain several instances of a dedicated module.
In general the different instances of such modules are identified by the index
“n”, where “n” counts from 0 to the number of instances minus one.
Legend
Symbols and notation are used as follows:
• Weight in data notation:
Left is high order column, right is low order
column
• Active low notation:
xxx (pin or signal name is over-scored) or
/xxx (slash before signal name)
• Memory map address:
High order at high stage and low order at low
stage
Note
Additional remark or tip
Caution
Item deserving extra attention
Numeric notation
• Binary:
xxxx or xxx

Diagrams
Block diagrams do not necessarily show the exact wiring in hardware but the
functional structure.
Timing diagrams are for functional explanation purposes only, without any
relevance to the real hardware implementation.
