255 This commit was manufactured by cvs2svn to create tag 'rel_0_5_beta'. 6556d 08h /t48/tags/rel_0_5_beta/rtl/
145 remove PROG and end of XTAL2, see comment for details arniml 7182d 13h /t48/tags/rel_0_5_beta/rtl/
144 delay db_dir_o by one machine cycle
this fixes the timing relation between BUS data and WR'		 arniml 7182d 13h /t48/tags/rel_0_5_beta/rtl/
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 7182d 14h /t48/tags/rel_0_5_beta/rtl/
142 deassert rd_q, wr_q and prog_q at end of XTAL3 arniml 7182d 14h /t48/tags/rel_0_5_beta/rtl/
138 Fix for:
P1 constantly in push-pull mode in t8048		 arniml 7184d 00h /t48/tags/rel_0_5_beta/rtl/
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 7226d 09h /t48/tags/rel_0_5_beta/rtl/
129 cleanup copyright notice arniml 7288d 16h /t48/tags/rel_0_5_beta/rtl/
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 7295d 20h /t48/tags/rel_0_5_beta/rtl/
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 7299d 12h /t48/tags/rel_0_5_beta/rtl/
119 add int_in_progress_o to entity of int module arniml 7299d 12h /t48/tags/rel_0_5_beta/rtl/
108 Fix for:
External Program Memory ignored when EA = 0		 arniml 7340d 11h /t48/tags/rel_0_5_beta/rtl/
107 tie EA to '1' arniml 7340d 11h /t48/tags/rel_0_5_beta/rtl/
106 clean-up use of ea_i arniml 7340d 11h /t48/tags/rel_0_5_beta/rtl/
101 assert p2_read_p2_o when expander port is read arniml 7343d 19h /t48/tags/rel_0_5_beta/rtl/
100 reorder data_o generation arniml 7343d 19h /t48/tags/rel_0_5_beta/rtl/
98 Fix bug "ANL and ORL to P1/P2 read port status instead of port output register" arniml 7343d 19h /t48/tags/rel_0_5_beta/rtl/
92 work around bug in Quartus II 4.0 arniml 7344d 18h /t48/tags/rel_0_5_beta/rtl/
91 fix edge detector bug for counter arniml 7344d 18h /t48/tags/rel_0_5_beta/rtl/
