arniml 5943d 13h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
220 new input xtal_en_i arniml 6623d 10h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
215 suppress p2_output_pch_o when MOVX operation is accessing the
external memory
arniml 6840d 14h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
214 fix sensitivity list arniml 6847d 15h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
204 * suppress p2_output_pch_o when p2_output_exp is active
* wire xtal_i to interrupt module
arniml 6853d 13h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
195 Suppress assertion of bus_read_bus_s when interrupt is pending.
This should fix bug report
"PROBLEM WHEN INT AND JMP"
arniml 6855d 01h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
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 6902d 14h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
179 introduce prefix 't48_' for all packages, entities and configurations arniml 6997d 01h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd

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 7225d 15h /t48/tags/rel_1_2/rtl/vhdl/decoder.vhd
134 Fix bug report:
"PSENn Timing"
PSEN is now only asserted for the second cycle if explicitely

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
