Background Debug Mode (BDM) Interface
Result Data:
The contents of the selected register are returned as a longword value. The data is returned most significant
word first.
20.3.4.1.2
WAREG and WDREG write the operand longword data to the specified address or data register. All 32
register bits are altered by the write. A bus error response is returned if the CPU core is not halted.
Command Format:
Command Sequence:
Operand Data:
Longword data is written into the specified address or data register. The data is supplied most significant
word first.
Result Data:
Command complete status is indicated by returning the data $FFFF (with the status bit cleared) when the
register write is complete.
20.3.4.1.3
The READ command reads the operand data from 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.
