System Memory Map

The ISD94100 series provides 4G-byte addressing space. The memory addresses assigned to
each on-chip controllers are shown in Table 6.2.7-1. The detailed register definition, memory space,
and programming will be described in the following sections for each on-chip peripheral. The
ISD94100 series only supports little-endian data format.
