Deactivation Sequencing
The host device can request a deactivation sequence
by resetting the START bit to 0 for the desired card
interface. The deactivation (from the deassertion of the
START bit, step 1 of the deactivation sequence, to
VCCx decrease to less than 0.4V) is less than 150s.
Emergency Deactivation
An emergency deactivation occurs if unsatisfactory
operating conditions are detected. An emergency deac-
tivation occurs for all activated cards in response to a
supply-voltage brownout condition (as reported by the
HSR.SUPL bit) or chip overheating (as reported by
HSR.PTL). Emergency deactivation of an individual card
can occur if a short-circuit condition is detected on the
associated VCCx or RSTx pin (as reported by
HSR.PRTLx) or in the case of a card takeoff (as reported
by HSR.PRLx). When an emergency deactivation occurs,
hardware automatically forces the associated START
bit(s) to the 0 state. The response of the device to the
emergency deactivation varies according to the source.
If the RSTx pin is shorted or the device overheats, the
sequencer executes a fast emergency deactivation
sequence, which ramps down VCCx immediately.
If the VCCx pin was shorted, the sequencer executes a
deactivation sequence in same way as if the START bit
was cleared to 0.
Interrupt Generation
The INT output pin signals the host device that an event
occurred that may require attention. The assertion of
the INT pin is a function of the following sources:
A fault has been detected on card interfaces
(A or B).
VDD has dropped below the acceptable level.
A reset is caused by externally driving the DELAY
pin to less than 1.25V.
Excessive heating is detected (i.e., PTL = 1).
A level change has been detected on pin PRESx or
INTAUX for the card interfaces (A, B, or AUX).
The parity and/or frame error is detected.
The early answer (EA) bit is set during ATR.
The timeout counter(s) reach their terminal
count(s).
The FIFO full status is reached.
The FIFO overrun occurs.
The transmit buffer is empty.
