0xBFFF

0xBFFF is a hexadecimal constant used in computing. It denotes the 16-bit unsigned integer whose decimal value is 49151. The hexadecimal digits BFFF map to the binary sequence 1011 1111 1111 1111. In memory, this value occupies two bytes in a 16-bit width.

It lies near the upper end of the 16-bit range, just before 0xC000 (49152).

In memory representation, the byte order matters: in big-endian order, the two bytes are 0xBF followed by 0xFF; in little-endian order, they appear as 0xFF followed by 0xBF.

The binary pattern of 0xBFFF is 1011 1111 1111 1111, with the lower 12 bits set to ones (0xFFF) and the upper nibble equal to 0xB. This combination can be encountered in bitwise masking schemes or as a high-range sentinel value in various legacy data formats or low-level software contexts, though the exact meaning depends on the system or protocol in use.
