Electrical Characteristics
4.3.20.2.2
The sequence of reset for this kind of card is as follows (see
86
1. After powerup, the clock signal is enabled on CLK (time T0)
2. After 200 clock cycles, RX must be high.
3. RST must remain Low for at least 40000 clock cycles after T0 (no response is to be received on
4. RST is set High (time T1)
5. RST must remain High for at least 40000 clock cycles after T1 and a response must be received
