7	Updated the asm files to test instructions running in RAM. Also added ram2k.mem needed to generate the lattice 2k RAM mapped 0 to $3ff.	stanley82	4886d 18h	/
6	IRQ, NMI fixed, shift instructions fixed. RAM increased to 2K, expanded usrcode.asm to test instructions, couple of instructions fixed clv, . Combined out_dat1 and out_dat2 into out_dat to save LUTs and updated jsr. Fixed stack to push down pull up per a real 6502. Processor sta irq and sta nmi trigger the interrupts see usrcode.asm.	stanley82	4886d 18h	/

3	At last I have some idea on updating my first set of revisions to the 65C02.vhd. See revision in file for details. CMP carry corrected. PHP corrected JSR changed, dat_out1, dat_out2 become dat_out wr_cnt becomes wr_fg recovers 43 slices. Setting flags in cycle(n) and (n+1) redundant and corrected	stanley82	4925d 15h	/
