Abstract

A timer for an A/D converter generates a request signal for A/D conversion by the A/D converter. In addition to the usual request signal, the timer produces a further signal which is used, before one cycle of the timer has elapsed, to block the A/D converter for low-priority requests from other requesting devices and to reserve it for the timer. In this manner, the signal to be converted from the timer can be sampled at reproducible, equidistant instants without having to wait for the end of the last conversion.
