205 operate ale_q and int_q with xtal_i after shift of ALE assertion to XTAL3 arniml 6851d 12h /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 6851d 12h /t48/tags/rel_1_1/rtl/vhdl/
203 * shift assertion of ALE and PROG to xtal3
* correct change of revision 1.8
arniml 6851d 13h /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 6853d 00h /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 6900d 13h /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 6900d 13h /t48/tags/rel_1_1/rtl/vhdl/
183 fix missing assignment to outclock arniml 6906d 16h /t48/tags/rel_1_1/rtl/vhdl/
180 introduce prefix 't48_' for wb_master entity and configuration arniml 6995d 00h /t48/tags/rel_1_1/rtl/vhdl/
179 introduce prefix 't48_' for all packages, entities and configurations arniml 6995d 00h /t48/tags/rel_1_1/rtl/vhdl/
178 Move latching of BUS to MSTATE2
-> sample BUS at the end of RD'
arniml 6996d 12h /t48/tags/rel_1_1/rtl/vhdl/
177 Implement db_dir_o glitch-safe arniml 6996d 12h /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 6996d 12h /t48/tags/rel_1_1/rtl/vhdl/
174 fix bug report
"MSB of Program Counter changed upon PC increment"
arniml 6997d 15h /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 7026d 11h /t48/tags/rel_1_1/rtl/vhdl/
171 remove obsolete output stack_high_o arniml 7027d 11h /t48/tags/rel_1_1/rtl/vhdl/
169 initial check-in arniml 7028d 23h /t48/tags/rel_1_1/rtl/vhdl/
168 change address range of wb_master arniml 7028d 23h /t48/tags/rel_1_1/rtl/vhdl/
167 simplify address range:
- configuration range
- Wishbone range
arniml 7028d 23h /t48/tags/rel_1_1/rtl/vhdl/
166 assign default for state_s arniml 7030d 15h /t48/tags/rel_1_1/rtl/vhdl/
165 add component wb_master.vhd arniml 7031d 14h /t48/tags/rel_1_1/rtl/vhdl/
164 initial check-in arniml 7031d 14h /t48/tags/rel_1_1/rtl/vhdl/
162 Fix bug report:
"Wrong clock applied to T0"
t0_o is generated inside clock_ctrl with a separate flip-flop running
with xtal_i
arniml 7032d 14h /t48/tags/rel_1_1/rtl/vhdl/
161 fix syntax problem that triggers an error with GHDL 0.18 arniml 7063d 18h /t48/tags/rel_1_1/rtl/vhdl/
157 removed obsolete constant arniml 7184d 14h /t48/tags/rel_1_1/rtl/vhdl/
156 added hierarchy t8039_notri arniml 7184d 14h /t48/tags/rel_1_1/rtl/vhdl/
155 initial check-in arniml 7184d 14h /t48/tags/rel_1_1/rtl/vhdl/
153 introduced generic gate_port_input_g
forces masking of P1 and P2 input bus
arniml 7185d 12h /t48/tags/rel_1_1/rtl/vhdl/
150 intruduced hierarchy t8048_notri where all system functionality
except bidirectional ports is handled
arniml 7186d 11h /t48/tags/rel_1_1/rtl/vhdl/
149 update arniml 7186d 11h /t48/tags/rel_1_1/rtl/vhdl/
148 initial check-in arniml 7186d 11h /t48/tags/rel_1_1/rtl/vhdl/
