AMC7823 MEMORY MAP
The AMC7823 has several 16-bit registers separated into two pages of memory, Page 0 and Page 1. The
memory map is shown in Table 2. Locations that are marked Reserved read back 0x0000 if they are read by the
host. Writing to these locations has no effect. Figure 40 explains the Read/Write operation.
