Objective of Manual and Target Audience
The MB90M405 Series is a general-purpose semiconductor device in the F
2
MC-16LX family. It is a 16-bit
single-chip microcontroller ASIC (Application Specific IC). This manual explains the functions and
operations of the MB90M405 Series for engineers who design products using this device.
How to Read This Manual
n
Page Organization
A summary is given below the title of each section. A title of the main section is noted in the sub-section to
recognize a current-reading section.
n
Index Organization
(1) Register map index
The register map index format is similar to the I/O map and it allows search for the page explaining the
bits of each register from the address, register abbreviation, register name, and resource macro name.
Use the register map index at searching for the register function when designing a resource macro.
(2) Pin function index
The pin function index is similar to the explanation of the pin function and it allows serch for the block
diagram of each resource macro, the explanation of the pin function, and notes from the package pin
number, pin name, circuit type, and resource macro name. Use the pin function index when creating
the system board, etc. (The pin function index will be provided in the next revision of this manual).
