188 update options to match what the ISE gui does davidgb 1224d 02h /System09/trunk/rtl
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1224d 07h /System09/trunk/rtl
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1224d 10h /System09/trunk/rtl
185 Reverted back to the single-step version - something was broken davidgb 1224d 11h /System09/trunk/rtl
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1224d 12h /System09/trunk/rtl

System boots but the baud clock must be wrong - get garbage on hyperterm.		 davidgb 1225d 01h /System09/trunk/rtl
174 Added button debounce. Single-step button. multiplex LED to show nibbles of addr and data for debug. Confirmed that CPU is reading from sys09swt.vhd SBug ROM correctly. Still need to debug ACIA output. davidgb 1225d 05h /System09/trunk/rtl
173 Add another 16k BRAM for 56K total memory davidgb 1227d 00h /System09/trunk/rtl

169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 1227d 12h /System09/trunk/rtl
