When a session is completed, the microcontroller sets the
CMDVCC line to HIGH state or MODE line to LOW state.
The circuit then executes an automatic deactivation
sequence by counting the sequencer down and thus end
in the Idle mode.
Figures 13 and 14 illustrate the deactivation sequence as
follows:
