143 Fix bug report:
"RD' and WR' not asserted for INS A, BUS and OUTL BUS, A"
rd is asserted for INS A, BUS
wr is asserted for OUTL BUS, A
P1, P2 and BUS are written in first instruction cycle
arniml 7260d 20h /t48/tags/rel_1_0/rtl/vhdl/
142 deassert rd_q, wr_q and prog_q at end of XTAL3 arniml 7260d 20h /t48/tags/rel_1_0/rtl/vhdl/
138 Fix for:
P1 constantly in push-pull mode in t8048
arniml 7262d 06h /t48/tags/rel_1_0/rtl/vhdl/
134 Fix bug report:
"PSENn Timing"
PSEN is now only asserted for the second cycle if explicitely
requested by assert_psen_s.
The previous implementation asserted PSEN together with RD or WR.
arniml 7304d 15h /t48/tags/rel_1_0/rtl/vhdl/
129 cleanup copyright notice arniml 7366d 22h /t48/tags/rel_1_0/rtl/vhdl/
128 counter_q is not cleared during reset
this would match all different descriptions of the Counter as
a) if the software assumes that the Counter is modified during reset, it
will initialize the Counter anyhow
b) the special case 'Counter not modified during reset' is covered
arniml 7374d 02h /t48/tags/rel_1_0/rtl/vhdl/
120 Fix bug report:
"Program Memory bank can be switched during interrupt"
int module emits int_in_progress signal that is used inside the decoder
to hold mb low for JMP and CALL during interrupts
arniml 7377d 18h /t48/tags/rel_1_0/rtl/vhdl/
119 add int_in_progress_o to entity of int module arniml 7377d 18h /t48/tags/rel_1_0/rtl/vhdl/
108 Fix for:
External Program Memory ignored when EA = 0
arniml 7418d 17h /t48/tags/rel_1_0/rtl/vhdl/
107 tie EA to '1' arniml 7418d 17h /t48/tags/rel_1_0/rtl/vhdl/
106 clean-up use of ea_i arniml 7418d 17h /t48/tags/rel_1_0/rtl/vhdl/
101 assert p2_read_p2_o when expander port is read arniml 7422d 01h /t48/tags/rel_1_0/rtl/vhdl/
100 reorder data_o generation arniml 7422d 01h /t48/tags/rel_1_0/rtl/vhdl/
98 Fix bug "ANL and ORL to P1/P2 read port status instead of port output register" arniml 7422d 01h /t48/tags/rel_1_0/rtl/vhdl/
92 work around bug in Quartus II 4.0 arniml 7423d 00h /t48/tags/rel_1_0/rtl/vhdl/
91 fix edge detector bug for counter arniml 7423d 00h /t48/tags/rel_1_0/rtl/vhdl/
86 update notice about expander port instructions arniml 7438d 03h /t48/tags/rel_1_0/rtl/vhdl/
78 adjust external timing of BUS arniml 7443d 23h /t48/tags/rel_1_0/rtl/vhdl/
77 move from std_logic_arith to numeric_std arniml 7444d 15h /t48/tags/rel_1_0/rtl/vhdl/
73 removed dummy_s - workaround not longer needed for GHDL 0.11.1 arniml 7445d 04h /t48/tags/rel_1_0/rtl/vhdl/
72 removed superfluous signal from sensitivity list arniml 7445d 04h /t48/tags/rel_1_0/rtl/vhdl/
66 add temporary workaround for GHDL 0.11 arniml 7450d 20h /t48/tags/rel_1_0/rtl/vhdl/
65 clean up sensitivity list arniml 7450d 20h /t48/tags/rel_1_0/rtl/vhdl/
64 + enhance instruction strobe generation
+ rework address output under EA=1 conditions
arniml 7450d 20h /t48/tags/rel_1_0/rtl/vhdl/
63 reset machine state to MSTATE3 to allow proper instruction fetch
after reset
arniml 7450d 20h /t48/tags/rel_1_0/rtl/vhdl/
62 initial check-in arniml 7450d 20h /t48/tags/rel_1_0/rtl/vhdl/
60 + add marker for injected calls
+ suppress intstruction strobes for injected calls
arniml 7453d 17h /t48/tags/rel_1_0/rtl/vhdl/
59 increment prescaler with MSTATE4 arniml 7453d 17h /t48/tags/rel_1_0/rtl/vhdl/
54 - add tb_istrobe_s arniml 7454d 18h /t48/tags/rel_1_0/rtl/vhdl/
