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
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.

Prefixes representing powers of 2 (address space, memory capacity):
• K (Kilo):
• M (Mega):
• G (Giga):
X, x = don't care
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.
