DESCRIPTIONREV APPROVEDDATE
01/07/03 RRP
Sheet 2: Changed LENDIAN_MODE signal so R221 is a pull-up and S2 provides
a pull-down.
Sheet 3: Swapped DSP_SCL0 and DSP_SDA0 signals going to U16.
Sheet 7: Added series terminations RN28, R246, R247, & R248.
Sheet 11: Routed DC_A[8:6], UART_CSA#, & UART_CSB# to U15.
Sheet 13: Changed bus routed to U53 to VP0D[9:2] and U52 to VP1D[9:2].
Sheet 15: Added pull-up (R241) to DC_ARDY.
Sheet 17: Pin 177 is Ground not VCC
Sheet 20: Changed U36 & U37 to SN74LVC1G125DCKR.
B 04/01/03 RRP
Sheet 2: Changed EMAC_ENABLE to autodect S2 is now 2 position switch.
Sheet 3: Routed FPGALOCK to pullup R101 to lock FPGA programming
Sheet 7: Implemented EMAC_ENABLE Autodetect on U41-1A, added R249
Sheet 11: Added TCE2# ,TCE3#, SOE3# to U15 Decoder.
Sheet 16: Swapped pins 141 and 149 on FPGA for HDTV speed paths, changed
fpga to -7 part
Sheet 17: Added AND Gate U55 to Lock FPGA programming, changed FPGA to -7
Sheet 20: Swapped Red and Blue on VGA Connector. Removed R102,R129,R183
Sheet 22: Added R250 for HPI option
