ASCII
: ASCII characters packed 2 per register in high, low order and without any
termination charcters.
Example
: “EPM6000” would be 4 registers containing 0x5378, 0x6172, 0x6B31,
0x3030.
SINT16/UINT16:
16-bit signed/unsigned integer.
SINT32/UINT32:
32-bit signed/unsigned integer spanning 2 registers. The lower-addressed
register is the high order half.
FLOAT:
32-bit IEEE floating point number spanning 2 registers. The lower-addressed
register is the high order half (i.e., contains the exponent).
