10 / 17 page  USB 2.0 ATA/ATAPI Controller Datasheet SMSC USB97C202 Page 10 Revision 1.2 (02-04-04) DATASHEET MISC General Purpose I/O GPIO[1:7] IO20 These general purpose pins may be used either as inputs, edge sensitive interrupt inputs, or outputs. When using internal ROM mode, these pins have the following assignments: GPIO1: USB HS Indicator; active high GPIO2: Serial EEPROM (93LC66 type) Chip Select GPIO3: USB VBUS Detect Input GPIO4: Serial EEPROM Data In/Out GPIO5: ATA Drive Reset GPIO6: A16 control line for external program Flash memory when using firmware upgrade capability (external ROM operation only) GPIO7: Serial EEPROM Clock output RESET input nRESET IS This active low signal is used by the system to reset the chip. The active low pulse should be at least 100ns wide. Test input nTest[0:2] IP These signals are used for testing the chip. User should normally leave them unconnected. For board testing, all pads except these test inputs are included in an XNOR chain, such that by tying nTEST2 low, nIOR will reflect the toggling of a signal on each pin. Circuit board continuity of the pin solder connections after assembly can be checked in this manner POWER, GROUNDS, and NO CONNECTS VDD +2.5V Core power VDDIO +3.3V I/O power VDDP +2.5 Analog power VSSP Analog Ground Reference VDDA +3.3V Analog power VSSA Analog Ground Reference GND Ground Reference NC No Connect. These pins should not be connected externally. |
