Figure 5: Asynchronous Activation Sequence – RSTIN Low When
CMDVCC Goes Low
The following steps list the activation sequence and the timing of the card control signals when the
system controller pulls the
CMDVCC low while the RSTIN is high:
1.
CMDVCC is set low.
2.
Next, the internal VCC control circuit checks the presence of VCC at t1. In normal operation, the
voltage VCC to the card becomes valid during this time. If not, OFF goes low to report a fault to the
system controller, and the power VCC
3.
Due to the fall of RSTIN at t
to the card is turned off.
2
4.
CLK is applied to the card at the end of t
, turn I/O (AUX1, AUX2) to reception mode.
3
5.
RST is to be a copy of RSTIN after t
after I/O is in reception mode.
4. RSTIN may be set high before t 4, however the sequencer
won’t set RST high until 42000 clock cycles after the start of CLK.
