Circuit arrangement for activation of circuit block, has clock controller interrupting clock for circuit blocks for preset period if detector detects that switched off block is activated, and switching on-/off device switching blocks

摘要

The arrangement has a switching on-/ off device (14) for switching on/off of circuit blocks (12, 13), and a detector (16) detecting if a switched off circuit block is activated. A clock controller (15) controls a clock pulse for circuit blocks and interrupts the clock for the blocks for a preset period if the detector detects that the block is activated. The switching on-/off device switches the blocks during the period. An independent claim is also included for a method of activation of a circuit block in an electronic circuit.
