The Define Word Data pseudo-operations generate the byte reversed form
for 16 bit constants.
The first byte is the low order half, followed by the high order byte.

.H 3 "Selection Criteria Keywords"
.VL 25 5
.LI R01
Only the reserved symbols R0 and R1 (or r0, r1) are acceptable as
the REG operand.
.LI R07
All the reserved symbols R0 thru R7 are acceptable as the REG operand.
.LE
.H 3 "Bit Operands"
Bit Addresses can be in two forms.
.P
One form is "expression.constant" where expression gives an address for a
bit addressable register and constant (in the range of 0 to 7) gives the
bit number in the byte.
Expression values must be either in the range of 20h to 2fh, or
the multiples of 8 between 80h and f8h, and defined in the first pass.
.P
The second form is an symbolic expression with value between 0 and 255.
The value of the expression is placed in the operand field of the
instruction without modification.
.H 3 "Apostrophes"
The apostrophes in the syntax field are a notation used for the
parser generator and are not put in the assembler source statement.
.H 2 "Notes"
.H 3 "Address Spaces"
The Four address spaces, Program Memory, Internal Data Memory, Bit Numbers,
and External Data Memory are not differentiated in the symbol table.
Which address space a symbol refers to is determined by the context of
the instruction operands it appears in.
