Data handling
bit
0
Data is handled as an unsigned 16-bit integer.
bit
0
Data is handled as an signed 16-bit integer.
If the sign bit (bit 15) is 1, the value is two's complement.
bit
0
Handled as an unsigned 32-bit integer with the starting address
number as the lower word.
Handled as a signed 32-bit integer with the starting address
number as the lower word.
If the sign bit (bit 31) is 1, the value is two's complement.
Data is handled as a four digit (16-bit) binary-coded decimal value.
bit
0 Each four bits from bit 0 to bit 11 is handled as the absolute value
for the 1st to 3rd digit.
Bit 12 to bit 15 is handled as the minus sign (-) when its value is F
(Hex) and it is handled as the absolute value for the 4th digit when
