208 Removed unnecessary package references jshamlet 1537d 03h /open8_urisc/trunk/
207 Added a simple 8-bit, fixed asynchronous serial interface with compile time settable bit-rate, parity enable, and parity mode generics. jshamlet 1537d 20h /open8_urisc/trunk/
206 Merged interrupt logic with other clocked process. jshamlet 1541d 15h /open8_urisc/trunk/
205 More code and comment cleanup for the new SDLC engine jshamlet 1541d 15h /open8_urisc/trunk/
204 Fixed more incorrect comments jshamlet 1541d 15h /open8_urisc/trunk/
203 Removed an extra delay FF from the bitclock rising edge signal for the clock slave configuration to better center the rising edge pulse on the receive signal. jshamlet 1541d 21h /open8_urisc/trunk/
202 Fixed receiver bug that caused false flag detection,
Split the large sdlc_serial_ctrl entity into sub-entities to make debugging easier.		 jshamlet 1541d 22h /open8_urisc/trunk/
201 Fixed comments regarding RX Checksum location jshamlet 1543d 19h /open8_urisc/trunk/
200 Renamed dual-port buffer to match other entities. jshamlet 1543d 20h /open8_urisc/trunk/
199 Added monitor ram for debugging and fixed issue with dual-port read path. jshamlet 1543d 20h /open8_urisc/trunk/
198 Removed debugging memory jshamlet 1544d 04h /open8_urisc/trunk/
197 Fixed incorrect comments jshamlet 1544d 04h /open8_urisc/trunk/
196 Modified the update logic to allow direct writes to offset 0xFE for refreshing the clock status. This way, any write to the clock status register will immediately be undone. (Writing 0x00 to offset 0xFF is once-more ignored) jshamlet 1544d 05h /open8_urisc/trunk/
195 Added dual-port RAM core for SDLC interface. jshamlet 1544d 23h /open8_urisc/trunk/
194 Cleaned up licensing sections jshamlet 1544d 23h /open8_urisc/trunk/
193 Fixed incorrect comment in o8_alu16.vhd. The value of the write to 0x1F doesn't matter, as the write itself triggers the calculation. jshamlet 1545d 00h /open8_urisc/trunk/
192 Added SDLC packet engine jshamlet 1545d 00h /open8_urisc/trunk/
191 Cleaned up comments, added back the OPEN8_NULLBUS constant, and added some new modules for ADCs and LCD displays.
Also made the button input module more configurable by moving the debounce code to a separate entity and using generics to instantiate it.		 jshamlet 1545d 00h /open8_urisc/trunk/
190 Fixed a bug in CPU where RTI/RTS wasn't idling the instruction cache, causing intermittent failures where RTI would execute as RTS, corrupting the stack;
Fixed a bug in the real-time clock where the uSec tick generator would stop if the PIT timer value was left/set to 0x00.		 jshamlet 1556d 22h /open8_urisc/trunk/
189 Merged changes from private repository,
added ceil_log2 function to Open8_pkg, since it is used to calculate RAM vectors,
cleaned up comments and removed local copies of the ceil_log2 function from peripherals.		 jshamlet 1557d 22h /open8_urisc/trunk/
