Address mapping
The ML87V3104 supports a 19-bit byte address for access from the host CPU. The 4M bit display memory and
the 32-byte control registers are mapped to this address.
When accessing the display memory, the bit assignment of the address is determined by the setting of the memory
size. (Fig. F5.2) See the next section for details of the control registers.
