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 7198d 04h /t48/tags/rel_1_0/rtl/vhdl/
142 deassert rd_q, wr_q and prog_q at end of XTAL3 arniml 7198d 04h /t48/tags/rel_1_0/rtl/vhdl/
138 Fix for:
P1 constantly in push-pull mode in t8048
arniml 7199d 15h /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.

129 cleanup copyright notice arniml 7304d 07h /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 7311d 11h /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 7315d 03h /t48/tags/rel_1_0/rtl/vhdl/
119 add int_in_progress_o to entity of int module arniml 7315d 03h /t48/tags/rel_1_0/rtl/vhdl/
108 Fix for:
External Program Memory ignored when EA = 0
arniml 7356d 02h /t48/tags/rel_1_0/rtl/vhdl/
107 tie EA to '1' arniml 7356d 02h /t48/tags/rel_1_0/rtl/vhdl/
106 clean-up use of ea_i arniml 7356d 02h /t48/tags/rel_1_0/rtl/vhdl/
101 assert p2_read_p2_o when expander port is read arniml 7359d 09h /t48/tags/rel_1_0/rtl/vhdl/
100 reorder data_o generation arniml 7359d 09h /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 7359d 10h /t48/tags/rel_1_0/rtl/vhdl/
92 work around bug in Quartus II 4.0 arniml 7360d 08h /t48/tags/rel_1_0/rtl/vhdl/
91 fix edge detector bug for counter arniml 7360d 08h /t48/tags/rel_1_0/rtl/vhdl/
86 update notice about expander port instructions arniml 7375d 12h /t48/tags/rel_1_0/rtl/vhdl/
78 adjust external timing of BUS arniml 7381d 08h /t48/tags/rel_1_0/rtl/vhdl/
77 move from std_logic_arith to numeric_std arniml 7382d 00h /t48/tags/rel_1_0/rtl/vhdl/
73 removed dummy_s - workaround not longer needed for GHDL 0.11.1 arniml 7382d 13h /t48/tags/rel_1_0/rtl/vhdl/
