  • Patent number: 11928022
    Abstract: A UART includes a transmission register, a receive register, a virtual remappable pin, a parity error check circuit to evaluate contents of the receive register for a parity error, and control logic to determine contents of the transmission register. The contents include underlying data and a parity bit based thereupon. The control logic is to route the contents through the first virtual remappable pin to the receive register. The control logic is to, before reception of the entire contents at the receive register, cause modified contents to be provided to the receive register. The modified contents are to cause a parity error. The modified contents are to include different underlying data or a different parity bit than the contents of the transmission register. The control logic is to determine whether the parity error check circuit detected the parity error.

  • Patent number: 11887864
    Abstract: Flat no-leads integrated circuit (IC) packages are formed with solder wettable leadframe terminals. Dies are mounted on die attach pads, bonded to adjacent leadframe terminal structures, and encapsulated in a mold compound. A laser grooving process removes mold compound from a leadframe terminal groove extending along a row of leadframe terminal structures. A saw step cut along the leadframe terminal groove extends partially through the leadframe thickness to define a saw step cut groove. Exposed leadframe surfaces, including surfaces exposed by the saw step cut, are plated with a solder-enhancing material. A singulation cut is performed along the saw step cut groove to define leadframe terminals with end surfaces plated with the solder-enhancing material. The laser grooving process may improve the results of the saw step cut, and the saw step cut may remove mold compound not removed by the laser grooving process.
