Background Debug Mode (BDM) Interface
Command Sequence:
Operand Data:
The single operand is the longword address of the requested memory location.
Result Data:
The requested data is returned as either a word or longword. Byte data is returned in the least significant
byte of a word result, with the upper byte undefined. Word results return 16 bits of significant data;
longword results return 32 bits. A value of $0001 (with the status bit set) is returned if a bus error occurs.
20.3.4.1.4
The WRITE command writes the operand data to the memory location specified by the longword address.
The address space is defined by the contents of the low-order 5 bits {TT, TM} of the BDM Address
Attribute Register (BAAR). The hardware forces the low-order bits of the address to zeros for word and
longword accesses to ensure that operands are always accessed on natural boundaries: words on
0-modulo-2 addresses, longwords on 0-modulo-4 addresses.
