Notes
|
|
-----
|
|
|
|
- At startup CPLD ROM is mapped to Z80 CPU address space 0x0000-0x003F, CPU begins execution at 0x0000
|
|
- CPLD ROM (CF bootstrap mode) reads CF Boot Loader (256B) from start of CF (MBR) to 0xB000 and runs it
|
|
- CF Boot Loader reads ZRC Monitor (4KB) from sectors 0xF8-0xFF of CF to 0xB400 and runs it
|
|
- User sends ZZRCC RomWBW Loader hex file (?KB) at 0x5000, then runs it using G5000
|
|
- User sends RomWBW ROM image (512KB) which is autoexecuted
|
|
|
|
|
|
;;- ZZRCC Monitor reads 512KB (RomWBW) from sectors 0x120-0x51F of CF into first 512KB of RAM
