  bart 9f74a9565f Fixed more MU I/O bugs. Updated everything from BCC except the ASM to work on new CPU. Added back flasher programs. Fixed LOAD/HI bug by using unsigned const16 instead. Updated assembler including hotfix for FPGC jumping to addr3 after UART bootloader is done. FPGC6 now basically fully works again! 2 年 前
  bart 207413dd90 Assembler only needs Int: function, fixed position of program lenght. Ported ROM and UART bootloader over from FPGC5. Updated documentation on interrupts. Added resets. Fixed bug in MU. Increased stack size. Tested everything in hardware. Probably some other fixes and things I forgot. 2 年 前
  bart 9662964536 Added back scripts for converting to spi.txt. Tested code to run from SPI flash, fixed cycle delay for SPI flash in output latch in MU which caused the bus_q to arrive a cycle later than bus_done. 2 年 前
