16. The power switch swap time assumes no decoupling capacitors on the VCC_Card pins.
17. tswap is the time required for the CH_Swap pin to swap host to SIM slot connections.
18. The I/O pin swap time assumes a push / pull driver; otherwise, the rise time (RC time constant) of an open-drain
driver masks the actual I/O pin switch time.
