DATA — Data Flag - Shows that data accompanies the command.
R/W — Read/Write Flag
BKGND — Hardware request to enter active background mode
W/B — Word/Byte Transfer Flag
BD/U — BDM Map/User Map Flag
The bits in the BDM instruction register have the following meanings
when a firmware command is executed.
H/F — Hardware/Firmware Flag
DATA — Data Flag – Shows that data accompanies the command.
Indicates whether BDM registers and ROM are mapped to addresses
$FF00 to $FFFF in the standard 64-Kbyte address space. Used only
by hardware read/write commands.
