5th generation hi-speed usb flash media and cir controller with integrated card power fets datasheet smsc USB2231/usb2232 13 revision 1.3 (07-12-05) datasheet chapter 6 pin descriptions this section provides a detailed description 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 active, 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 asserted 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? sig nal. the term assert, or assertion indicates that a signal is active, independent of whether that level is represented by a high or low voltage. the term negate, or negation indicates that a signal is inactive. 6.1 pin descriptions table 6.1 USB2231/usb2232 pin descriptions name symbol buffer type description compactflash (in true ide mode) interface cf chip select 1 cf_ncs1 o8pu this pin is the active low chip select 1 signal for the cf ata device cf chip select 0 cf_ncs0 o8pu this pin is the 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 this pin is the register select address bit 1 for the cf ata device cf register address 0 cf_sa0 o8 this pin is the register select address bit 0 for the cf ata device. cf interrupt cf_irq ipd this is the active high interrupt request signal from the cf device. cf data 15-8 cf_d[15:8] i/o8pd the bi-directional data signals cf_d15-cf_d8 in 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 data7-0 cf_d[7:0] i/o8pd 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. io ready cf_iordy ipu this pin is active high input signal. this pin has an internally controlled weak pull-up resistor.
