WebOr, just connect the peripheral's 16bits to Bus2IP_data(31 downto 16) and also to Bus2IP_data(15 downto 0). AXI uses a byte-invariant endian scheme so the receiving master will know which bits to grab from the 32bit data bus during a 16bit read. Below is an example of accesses to a 32bit register within a 32bit axi-lite core.
