124 fix wrong handling of MB after return from interrupt arniml 7348d 05h /
123 support hex file for external ROM arniml 7348d 05h /
122 test MB after return from interrupt arniml 7348d 05h /
121 update bug description for
Program Memory bank can be switched during interrupt
arniml 7350d 22h /
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 7350d 22h /
119 add int_in_progress_o to entity of int module arniml 7350d 22h /
118 test MB/interrupt behaviour according to bug report
"Program Memory bank can be switched during interrupt"
arniml 7350d 22h /
117 add bug
Program Memory bank can be switched during interrupt
arniml 7351d 23h /
116 adapt to GHDL 0.12 / gcc 3.4.0 arniml 7379d 23h /
115 extend description arniml 7381d 03h /
114 initial check-in arniml 7384d 23h /
113 generate two ROM files based on address:
+ 0 - 2047 : 2k internal ROM
+ 2048 - 4095 : 2k external ROM
arniml 7391d 08h /
112 update tb_behav_c0 for new ROM layout arniml 7391d 08h /
111 split 4k internal ROM into
+ 2k internal ROM
+ 2k external ROM
EA of t48_core is driven by MSB of internal ROM address
if upper 2k block is selected, the system switches to EA mode on the fly
arniml 7391d 08h /
110 exchange syn_rom for lpm_rom arniml 7391d 08h /
109 add new bug for release 0.1 BETA arniml 7391d 21h /
108 Fix for:
External Program Memory ignored when EA = 0
arniml 7391d 21h /
107 tie EA to '1' arniml 7391d 21h /
106 clean-up use of ea_i arniml 7391d 22h /
