SIO1007
DCLK_33– D1
When DCLK_33 bit is asserted ‘1’, the bi-directional switch for the dedicated docking PCICLK will be switched on and
the DLPC_CLK_33 pin will be connected to the LPC_CLK_33 pin. When DCLK_33 bit is deasserted ‘0’, the DLPC_-
CLK_33 pin will be disconnected from the LPC_CLK_33 pin and the DLPC_CLK_33 pin will be an open circuit.
Note: The PCICLK signals are not bi-directional however, the switch only provides a low series impedance
(10).
DCLK_14– D2
When DCLK_14 bit is asserted ‘1’, the buffer is enabled and the DSIO_14M pin will provide a buffered version
DSIO_14M pin. When DCLK_14 bit is deasserted ‘0’, the DSIO_14M pin will be tri-stated.
