Rev	Log message	Author	Age	Path
243	Optimized code to prefer RAM vs register.	jshamlet	1513d 16h	/
242	Added write protect logic to the RAM cores and system timer as part of scheme to keep tasks from messing up the scheduler or other task's memory. The RAM is now divided into regions with a separate write mask register. The write mask register itself is only writeable with the I bit is set (during an interrupt or by setting it using STP PSR_I). The 1K memory is divided into 16, 64 byte regions while the 4K memory is divided into 32, 128 byte regions. The system timer simply checks for the I bit being set when the write protect generic is set. Note that setting the write_protect generic false, or leaving it unset, will keep the previous behavior.	jshamlet	1513d 17h	/
241	Added an Open8 compatible 7-segment display/decoder and uploaded local/private documentation.	jshamlet	1518d 12h	/
240	Simplified the vector tx/rx system to a single line. An idle detector replaces the attn_req signal.	jshamlet	1520d 16h	/
239	More cleanup and notation of board to board I/O	jshamlet	1520d 21h	/
238	Removed extraneous reference to Ints.VEC_Flag from task.s, since it is supposed to be in the init function in test_fn.s.	jshamlet	1521d 16h	/
237	Found some errors in the comments and cleaned up unnecessary library references.	jshamlet	1521d 18h	/
236	More software cleanup for the Open8_II project	jshamlet	1521d 19h	/
235	Ok, this time with feeling.	jshamlet	1526d 14h	/
234	Forgot to add documentation	jshamlet	1526d 16h	/
