W5500 buffer size for one socket

W5500 has internal 32kB Memory for TX/RX Buffers. If I use only one socket can I set TX buffer to 16kB and RX buffer to 16kB?

Any combination, with the sole restriction that a certain buffer size must be a power of 2 (1,2,4,8,16,32).
And, of course, the sum of all buffers sizes must be less or equal to 32.
