Abstract
Official abstract text for this publication.
A microcontroller unit having a functional state, a reset state, and one or more assertable fault sources is described. Each fault source has its own fault source assertion count and its own fault source assertion limit; the MCU is arranged to perform the following sequence of operations in a cyclic manner: if one or more of the fault sources are asserted, pass from the functional state to the reset state and increase the respective fault source assertion counts by one increment; if one or more of the fault source assertion counts exceeds the respective fault source assertion limit, disable the respective fault source; and pass from the reset state to the functional state. A method of operating an MCU is also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A microcontroller unit comprising: a functional state; a reset state; and one or more assertable fault sources, wherein each fault source has its own fault source assertion count and its own fault source assertion limit, and the MCU is arranged to cyclically pass from the functional state to the reset state and increase the fault source assertion counts of the asserted fault sources by one increment if one or more of the fault sources are asser…
