Emergency deactivation sequence on SCn interface (n=1, 2, 3, 4, 5)

AT83C26
•
•
It is a self-timed sequence which cannot be interrupted when started (see Figure 17). Each step
is separated by a delay based on Td equal to 8 periods of DCCLK, typically 2 to 2.4 µs:
Notes:
The card emergency automatic deactivation is triggered when one the following condition
occurs:
•
•
If the power supply is disconnected, a standard deactivation is started when VCC = VPFDP.
When VCC is equal to VPFDM, the emergency deactivation occurs and eventually ends the
standard deactivation.
