Reset Sequence
5.17.2.1
Cards with Internal Reset
The reset sequence for this kind of SIM card is as follows (see Figure 31):
After powerup, the clock signal is enabled on SIM_CLK (time T0)
After 200 clock cycles, RX must be high.
The card must send a response on RX acknowledging the reset between 400 and 40,000 clock cycles after T0.
Figure 31. Internal-Reset Card Reset Sequence
5.17.2.2
Cards with Active-Low Reset
The sequence of reset for this kind of card is as follows (see Figure 32):
1.
After powerup, the clock signal is enabled on SIM_CLK (time T0)
2.
After 200 clock cycles, RX must be high.
3.
SIM_RST must remain low for at least 40,000 clock cycles after T0 (no response is to be received on RX during those
40,000 clock cycles)
4.
SIM_RST is set high (time T1)
5.
SIM_RST must remain high for at least 40,000 clock cycles after T1 and a response must be received on RX between
400 and 40,000 clock cycles after T1.
