Implementations are disclosed for a centralized peripheral access controller (PAC) that is configured to protect one or more peripheral components in a system. In some implementations, the PAC stores data that can be set or cleared by software. The data corresponds to an output signal of the PAC that is routed to a corresponding peripheral component. When the data indicates that the peripheral is 'unlocked' the PAC will allow write transfers to registers in the peripheral component. When the data indicates that the peripheral component is 'locked' the PAC will refuse write transfers to registers in the peripheral component and terminate with an error.

Centralized peripheral access protection

A flexible-width peripheral register mapping is disclosed for accessing peripheral registers on a peripheral bus.

Peripheral registers with flexible data width

A device comprises a central processing unit (CPU), a display controller configured for controlling a digital display and a memory configured for storing data corresponding to the digital display. The device includes a direct memory access (DMA) controller configured for autonomously transferring the data from the memory directly to the display controller without CPU intervention.

Automating digital display

A microcontroller for controlling a liquid crystal display (LCD) is mountable in any one of multiple package types. The microcontroller includes a LCD controller to generate logical mapping signals indicative of voltages to be applied to segment terminals of a LCD glass. A driver circuit drives the segment terminals selectively. A remapping unit receives the logical mapping signals from the LCD controller and maps the logical mapping signals, for each of the package types, to physical segment terminal drivers in the driver circuit based on a distribution of I/O terminals that are bonded for each package type when that package type is used with the LCD glass.

Package dependent segment terminal remapping for driving liquid crystal displays

A process for automatically detecting and configuring with the throughput of a network, in which a device: (a) goes into a listen mode; (b) obtains a triplet of successive transitions in a transmitted signal, the triplet delimiting first and second signal levels, one dominant and the other recessive; (c) measures the duration of each of the first and second levels; (d) as a function of the measured durations, obtains a new throughput configuration by determining values for parameters that define a bit length L; (e) validates the new throughput configuration; (g) if at least one throughput adaptation condition is verified, goes into a normal mode, otherwise obtains a next transition of the signal, which delimits with the last previous transition a new level of the signal, then measures the duration of the new level and reiterates steps (d) to (g) taking account of the new signal level.
