Systems and methods for multi-protocol serial communication interfaces are described. One example system includes an interface module including a buffer for storing a protocol selection. The system includes a protocol module coupled to the interface module and configured for providing one or more serial communication protocols. Based on the protocol selection, one of the serial communication protocols is selected. The system also includes a serial engine module coupled to the interface module and the protocol module. The serial engine module is configured for transmitting and receiving data or commands based on the selected serial communication protocol.

A microcontroller system is organized into power domains. A power manager of the microcontroller system can change the power configuration of a power domain in response to event from an event generating module without activating a processor of the microcontroller system.

A circuit is disclosed that provides a programmable hold time for a bus signal without running a system clock and without a frequency requirement between the system clock and a bus clock.

Various embodiments include methods and related media for performing operations including a return operation. One such method includes testing a content of a return value register and setting status flags. Testing the content of the return value register and setting the status flags are performed in response to a single instruction.

A USB device can be configured for multi-packet data transfer to and from endpoints with minimal software intervention. Minimal software intervention allows a Central Processing Unit (CPU) of the USB device to handle other tasks, maximizing USB bus utilization.

Autonomous multi-packet transfer for universal serial bus

A driver circuit for a display device (e.g., an LCD) omits buffers and a resistive ladder and connects the output of a switched regulator directly to a display device through a selector switch. Voltage inputs for the display device can be selectively coupled to the output of the switched regulator using the selector switch. Each voltage input can be coupled to a capacitor that is charged when the corresponding voltage input is coupled to the high voltage output of the switched regulator. In some implementations, bypass switches are connected between the voltage inputs. If the voltage of a given capacitor is too high, the excess voltage can be transferred or otherwise discharged through the bypass switch to another capacitor storing a lower voltage.
