Bit - 0, 1
String(S) -
String data. It handles from the beginning to the NULL(00h) character as a
character string.
Data type Data handling
UBIN16(W) Data is handled as an unsigned 16-bit integer.
BIN16(I)
Data is handled as an signed 16-bit integer.
If the sign bit (bit 15) is 1, the value is two’s complement.
UBIN32(D)
Handled as an unsigned 32-bit integer with the starting address
number as the lower word.
BIN32(L)
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.
BCD4(B)
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).
