smsc usb97c211 page 12 revision 1.3 (11-05-03) datasheet 5 pin descriptions this section provides a detailed descr iption of each signal. the signals are arranged in functional groups according to their associated interface. the ?n? symbol in the signal name indicates that the acti ve, or asserted state occurs when the signal is at a low voltage level. when ?n? is not present before the signal name, the signal is a sserted when at the high voltage level. the terms assertion and negation are used exclusively. this is done to avoid confusion when working with a mixture of ?active low? and ?active high? signal. the term assert, or assertion indicates that a signal is active, independent of whether that level is repr esented by a high or low voltage. the term negat e, or negation indicates that a signal is inactive. 5.1 pin descriptions name symbol buffer type description compactflash (in true ide mode) interface cf chip select 1 cf_ncs1 o8 this pin is t he active low chip select 1 signal for the cf ata device cf chip select 0 cf_ncs0 o8 this pin is t he active low chip select 0 signal for the task file registers of cf ata device in the true ide mode. cf register address 2 cf_sa2 o8 this pin is the register select address bit 2 for the cf ata device. cf register address 1 cf_sa1 o8 address si gnal 1 for the task file registers, when the cfc is enabled in true ide mode cf register address 0 cf_sa0 o8 address signal 0 for the task file registers, when the cfc is enabled in true ide mode. cf interrupt cf_irq ipd this is the ac tive high interrupt request signal from the cf device. this pin has an internal weak pull-down resistor. cf data 15-8 cf_d[15:8] io8 the bi-directional data signals cf_d15-cf_d8 in true ide mode data transfer, when the cfc is enabled. 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]. these pins have an internal weak pull-down resistor. cf data7-0 cf_d[7:0] io8 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]. these pins have an internal weak pull-down resistor. io ready cf_iordy ipu this pin is active high input signal with an internal weak pull-up resistor. cf card detection2 cf_ncd2 ipu this card detection pi n is connected to the ground on the cf device, when the cf device is inserted. this pin has an internal weak pull-up resistor. cf card detection1 cf_ncd1 ipu this card detection pin is connected to ground on the cf device, when the cf device is inserted. this pin has an internal weak pull-up resistor.
