The clock can also be applied to the card using a RSTIN
mode allowing controlling the clock starting by setting
RSTIN Low (Figure 4). Before running the activation
sequence, that is before setting Low CMDVCC RSTIN is set
High. In these initial conditions CRD_CLK starts when
RSTIN is pulled Low. This allows a precise count of clock
pulses before toggling CRD_RST High for ATR
(Answer To Reset) request.
The internal activation sequence activates the different
channels according to a specific hardware builtit sequencing
internally defined but at the end the actual activation
sequencing is the responsibility of the application software
and can be redefined by the microcontroller to comply with
the different standards and the different ways the standards
manage this activation (for example light differences exist
between the EMV and the ISO7816 standards).
