’AIC26 MEMORY MAP
The ’AIC26 has several 16-bit registers which allow control of the device as well as providing a location for results from
the ’AIC26 to be stored until read by the host microprocessor. These registers are separated into three pages of memory
in the ’AIC26: a data page (Page 0) and control pages (Page 1 and Page 2). The memory map is shown in Table 6.
