205 operate ale_q and int_q with xtal_i after shift of ALE assertion to XTAL3 arniml 6825d 18h /t48/tags/rel_1_1/rtl/vhdl/
204 * suppress p2_output_pch_o when p2_output_exp is active
* wire xtal_i to interrupt module
arniml 6825d 18h /t48/tags/rel_1_1/rtl/vhdl/
203 * shift assertion of ALE and PROG to xtal3
* correct change of revision 1.8
arniml 6825d 18h /t48/tags/rel_1_1/rtl/vhdl/
195 Suppress assertion of bus_read_bus_s when interrupt is pending.
This should fix bug report
"PROBLEM WHEN INT AND JMP"
arniml 6827d 05h /t48/tags/rel_1_1/rtl/vhdl/
188 move check for int_pending_s into ea_i_='0' branch
this fixes a glitch on PCH when an interrutp occurs
during external program memory fetch
arniml 6874d 18h /t48/tags/rel_1_1/rtl/vhdl/
187 Fix bug reports:
"Target address of JMP to Program Memory Bank 1 corrupted by interrupt"
"Return address of CALL to Program Memory Bank 1 corrupted by interrupt"
int_in_progress_o was active one cycle before int_pending_o is
asserted. this confused the mb multiplexer which determines the state of
the memory bank selection flag
arniml 6874d 18h /t48/tags/rel_1_1/rtl/vhdl/
183 fix missing assignment to outclock arniml 6880d 21h /t48/tags/rel_1_1/rtl/vhdl/
180 introduce prefix 't48_' for wb_master entity and configuration arniml 6969d 05h /t48/tags/rel_1_1/rtl/vhdl/
179 introduce prefix 't48_' for all packages, entities and configurations arniml 6969d 05h /t48/tags/rel_1_1/rtl/vhdl/
178 Move latching of BUS to MSTATE2
-> sample BUS at the end of RD'
arniml 6970d 17h /t48/tags/rel_1_1/rtl/vhdl/
177 Implement db_dir_o glitch-safe arniml 6970d 17h /t48/tags/rel_1_1/rtl/vhdl/
176 Use en_clk_i instead of xtal3_s for generation of external signals.
This is required when the core runs with full xtal clock instead
of xtal/3 (xtal_div_3_g = 0).
arniml 6970d 17h /t48/tags/rel_1_1/rtl/vhdl/
174 fix bug report
"MSB of Program Counter changed upon PC increment"
arniml 6971d 20h /t48/tags/rel_1_1/rtl/vhdl/
172 save data from wishbone bus in register bank with wb_ack
necessary to hold data from peripheral/memory until it is read by T48
arniml 7000d 16h /t48/tags/rel_1_1/rtl/vhdl/
171 remove obsolete output stack_high_o arniml 7001d 17h /t48/tags/rel_1_1/rtl/vhdl/
169 initial check-in arniml 7003d 04h /t48/tags/rel_1_1/rtl/vhdl/
168 change address range of wb_master arniml 7003d 04h /t48/tags/rel_1_1/rtl/vhdl/
167 simplify address range:
- configuration range
- Wishbone range
arniml 7003d 04h /t48/tags/rel_1_1/rtl/vhdl/
166 assign default for state_s arniml 7004d 20h /t48/tags/rel_1_1/rtl/vhdl/
165 add component wb_master.vhd arniml 7005d 19h /t48/tags/rel_1_1/rtl/vhdl/
