Micro - electronic circuit of the activation or deactivation of at least one input / output, a chip card reader and the deactivation of the corresponding

摘要

The invention relates to a micro - electronic circuit activation or deactivation of at least two buffers of at least one electronic component. The second buffer receives a deactivation command corresponding to a combination of an activation command, respectively for the deactivation, general information representative of the activated state, respectively, inactivated, of at least a first buffer, so that the said second buffers are not activated or deactivated, that when the said first buffers are already been activated and deactivated, in order to comply with a predetermined sequence of activation or deactivation of said buffers.
