Notes on using EIOS on MB90500-
Series Devices
Fujitsu Microelectronics Europe GmbH, Microcontroller Application Group


Some core changes have been done, when developing the LX-family from the L-family. One
is the optimised interrupt behaviour, which reduces stack operations. However, there is one
specific case, which has to be taken into consideration, if schedulers or operating systems
have to be implemented for MB90500 series MCU. In case of usage of the Extended
Intelligent IO Service (EIOS) the way of storing data on stack can change. The application
note explains the different behaviour under different conditions.
The optimi
