11 / 23 page 4th Generation USB 2.0 Flash Media Controller with Integrated Card Power FETs Datasheet SMSC USB2226 11 Revision 1.4 (10-08-07) DATASHEET CF_D[7:0] 39 38 37 36 35 34 33 32 I/O8PD CF Data 7-0: The bi-directional data signals CF_D7-CF_D0 in the True IDE mode data transfer. In the True IDE Mode, all of task file register operation occur on the CF_D[7:0], while the data transfer is on CF_D[15:0]. The bi-directional data signal has an internal weak pull-down resistor. CF_IORDY 56 IPU IO Ready: This pin is active high input signal. This pin has an internally controlled weak pull-up resistor. CF_nCD2 54 IPU CF Card Detection2: This card detection pin is connected to the ground on the CF device, when the CF device is inserted. This pin has an internally controlled weak pull-up resistor. CF_nCD1 53 IPU CF Card Detection1: This card detection pin is connected to ground on the CF device, when the CF device is inserted. This pin has an internally controlled weak pull-up resistor. CF_nRESET 59 O8 CF Hardware Reset: This pin is an active low hardware reset signal to CF device. CF_nIOR 57 O8 CF IO Read: This pin is an active low read strobe signal for CF device. CF_nIOW 58 O8 CF IO Write Strobe: This pin is an active low write strobe signal for CF device. SmartMedia INTERFACE SM_nWP 74 O8PD SM Write Protect: This pin is an active low write protect signal for the SM device. This pin has a weak pull-down resistor that is permanently enabled. SM_ALE 73 O8PD SM Address Strobe: This pin is an active high Address Latch Enable signal for the SM device. This pin has a weak pull-down resistor that is permanently enabled. SM_CLE 75 O8PD SM Command Strobe: This pin is an active high Command Latch Enable signal for the SM device. This pin has a weak pull-down resistor that is permanently enabled.
