EXTERNAL MEMORY MAP
The external memory map is the
only
way to gain access to the
four channel address register pages and the output port control
register page. This set of eight registers is shown in Table 22.
These registers are collectively referred to as the external
memory map registers, because they control all accesses to the
channel address space as well as output control registers.
Rev. 0 | Page 55 of 76
The use of each of these individual registers is described in
detail in the following sections. It should be noted that the serial
control interface has the same memory map as the microport
interface and can carry out exactly the same functions, although
at a slower rate.
