RREFHSIC

I/O HSIC Strobe

I/O HSIC Data

I HSIC reference resistor input. If HSIC is used,

connect this pin to ground via a 51-ohm 5% resistor.

On SDIO designs this pin should not be connected.

WLAN GPIO Interface

Note: The GPIO signals can be multiplexed via software and the JTAG_SEL pin to support other functions.

See Table 23: âWLAN GPIO Functions and Strapping Options,â on page 119 and Table 26: âGPIO Alternative

Signal Functions,â on page 120 for additional details.
