The data is located at bit [7:0] when the data size of Host CPU is 8-bit, the address bit 0 (A0) = 1 is to
access the register data bit [15:8], A0 = 0 to access data bit [7:0].
Host Interface Type 2:
The Host interface type 2 is selected when XTYP pin is high. The data size of the CPU data bus may
be 16-bit or 8-bit and the access cycle may be in 3-cycle or 3-cycle. Figure 7-4 shows the timing of 16-
bit CPU read write in type 2 and the access cycle is 3-cycle access, figure 7-5 shows the timing of 16-
bit CPU read write in type 2 and the access cycle is 2-cycle access.
