摘要： A universal asynchronous receiver/transmitter (UART) interface is disclosed. The UART interface may include a configurable asynchronous receiver and transmitter unit; and a configurable state machine, wherein the state machine allows configuration of the receiver and transmitter unit to support various baud rates and provide for start bit and stop bit configuration, wherein the state machine is further configurable to automatically support a plurality of communication protocols.

摘要： An operational amplifier with totem pole connected output transistors having inputs coupled to multiplexers for selectable coupling of signals and voltage levels thereto. The high and low output transistors may be forced hard on or hard off in addition to normal coupling of signals thereto. The operation of the output transistors may be dynamically changed to pass only positive going signals, negative going signals, placed in a tristate high impedance state, hard connected to a supply voltage and/or hard connected to supply common return. A core independent peripheral (CIP) may also be coupled to the operational amplifier for dynamically changing the multiplexer inputs in real time, as can external control signals to a control circuit coupled to the multiplexers.
