This document describes the silicon updates to the functional specifications for FM3
MB9AA30N/MB9A130N series, MB9AB40NA/MB9AA40NA/MB9A340NA/MB9A140NA
series, MB9A150R series microcontrollers.
1. Description
Considering the characteristic of the maximum rise time (250µs) for CEC output signal of HDMI-CEC
standard, the period of arbitration lost detection was changed.

3. The period of arbitration lost detection
When detecting the difference between a data on CEC bus and a send data by 32 kHz sampling, identify an
arbitration lost occurs.
3.1
Original
The period of arbitration lost detection is as follows:
-
From the start of the “0” output until the end of the “1” output period.

3.2
Modification
The period of arbitration lost detection is changed as follows:
-
During the “1” out put from 300µs(10 clock) after the bus data rises to high

The products described in this document are designed, developed and manufactured as contemplated for general use,
including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not
designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless
extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury,
severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control,
mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where
chance of failure is intolerable (i.e., submersible repeater and artificial satellite). Please note that Spansion will not be liable
to you and/or any third party for any claims or damages arising in connection with above-mentioned uses of the products.
Any semiconductor devices have an inherent chance of failure. You must protect against injury, damage or loss from such
