Abstract

An analog to digital conversion includes a multiplexor circuit for receiving analog input signals and, responsive to a select input, an analog to digital converter circuit to convert a selected analog signal into a digital signal, a conversion starting device to send a conversion start signal on the basis of a trigger event, the conversion starting device being responsive to a select input, a sequencer to control the analog to digital converter circuitry to execute one sequence conversion on the basis of one conversion sequence instruction, and a FIFO register block to receive conversion sequence instructions and being able to queue each new received conversion sequence instruction if an actual conversion sequence is in progress and to control the sequencer to execute a new sequence conversion instruction after the conversion sequence is executed.

First claim

We claim:

1. An analog to digital conversion apparatus comprising:
a first multiplexor circuit for receiving a plurality of analog signals;
a second multiplexor circuit for receiving a plurality of triggering signals;
a third multiplexor circuit for receiving a plurality of masking signals;
an analog to digital converter circuit for receiving an analog signal from an output of the first multiplexor, and for providing a digital output signal;
a logic circuit coupled to outp…
