Table 8.9
Notes: The MXC1=1, MX0=1 setting is reserved. Do not use it.
For example, when MXC1 and MXC0 are set to 00 and an 8-bit shift is selected, the A23–A8
address bit values are output to pins A15–A0 as row addresses. The values for A21–A16 are
undefined. The values of bits address A21–A0 are output to pins A21–A0 as column addresses.
Figure 8.16 depicts address multiplexing with an 8-bit shift.
