Reset Sequence

3.7.12.1.1

Cards with internal reset

The sequence of reset for this kind of SIM Cards is as follows (see Figure 82):

•

After power up, the clock signal is enabled on SIMx_CLKy(time T0)

•

After 200 clock cycles, RX must be high.

•

The card must send a response on RX acknowledging the reset between 400 and 40000 clock

cycles after T0.

3.7.12.1.2

Cards with Active Low Reset

The sequence of reset for this kind of card is as follows (see Figure 83):

•

After power-up, the clock signal is enabled on SIMx_CLKy (time T0)

•

After 200 clock cycles, SIMx_DATAy_RX_TX must be high.

•

SIMx_RSTy must remain Low for at least 40000 clock cycles after T0 (no response is to be

received on RX during those 40000 clock cycles)

•

SIMx_RSTy is set High (time T1)

•

SIMx_RSTy must remain High for at least 40000 clock cycles after T1 and a response must be

received on SIMx_DATAy_RX_TX between 400 and 40000 clock cycles after T1.
