SIM Slot Signals: Active vs. 3-State
The individual SIM slot signals (CLK, RST, and I/O) are
active only if the appropriate VCCn
and VCC_H_n
supplies are active (1.65V – 3.6V).
For example, if EN=1 and CH_Swap is 1, SIM Slot 1
signals (CLK_1, RST_1, and I/O_1) are active only if
VCC1 and VCC_H_1 are both active (1.65V – 3.6V).
VCC1 sets the voltage levels of CLK_1, RST_1, and
I/O_1. If either VCC1 or VCC_H_1 is below 1.65V, SIM
Slot 1 signals (CLK_1, RST_1, and I/O_1) are high
impedance. Likewise, SIM Slot 2 signals (CLK_2,
RST_2, and I/O_2) are active only if both VCC2 and
VCC_H_2 are active (1.65V – 3.6V). VCC2 sets the
voltage levels of CLK_2, RST_2, and I/O_2.
If EN=1 and CH_Swap is 0, SIM Slot 1 (CLK_1, RST_1,
and I/O_1) signals are active only if VCC2 and
VCC_H_2 are active (1.65V – 3.6V). VCC2 sets the
voltage levels of CLK_1, RST_1, and I/O_1. Likewise,
SIM Slot 2 signals (CLK_2, RST_2, and I/O_2) are
active only if both VCC1 and VCC_H_1 are active
(1.65V – 3.6V). VCC1 sets the voltage levels of CLK_2,
RST_2, and I/O_2.

and signal combinations, see Table 8.
