WindLDR data types are displayed as follows: BIN16(+) as W (word), BIN16(+/-) as I (integer), BIN32(+)
as D (double word), BIN32(+/-) as L (long), and float32 as F (float).
Data type Data handling
BIN16 (+) Data is handled as an unsigned 16-bit integer.
BIN16 (+/-)
Data is handled as an signed 16-bit integer.
If the sign bit (bit 15) is 1, the value is two’s complement.
BIN32 (+)
Handled as an unsigned 32-bit integer with the starting address
as the lower word.
BIN32 (+/-)
Handled as a signed 32-bit integer with the starting address as
the lower word.
If the sign bit (bit 31) is 1, the value is two’s complement.
BCD4
Data is handled as a four digit (16-bit) binary-coded decimal
value.
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 0 to 9 (hex).
BCD8
Data is handled as an eight digit (32-bit) binary-coded decimal
value.
Each four bits from bit 0 to bit 27 is handled as the absolute
value for the 1st to 7th digit.
Bit 28 to bit 31 is handled as the minus sign (-) when its value is
F (hex) and it is handled as the absolute value for the 8th digit
when 0 to 9 (hex).
