Preface
This manual is intended for users who want to understand the functions of the
concerned microcontrollers.
This manual presents the hardware manual for the concerned microcontrollers.
This system specification describes the following sections:
• Pin function
• CPU function
• Internal peripheral function
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.
Symbols and notation are used as follows:
• Weight in data notation:
• Active low notation:
• Memory map address:
Additional remark or tip
Item deserving extra attention
• Binary:
• Decimal:
• Hexadecimal:
representing powers of 2 (address space, memory capacity):
• K (kilo):
• M (mega):
• G (giga):
X, x = don't care
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.
