ADSP-BF533 EZ-KIT Lite Evaluation System Manual 2-3
Using EZ-KIT Lite
The Flash memory is implemented with two Dual-Bank Flash Memory
devices. These devices include primary and secondary Flash memory as
well as internal SRAM and registers. Primary Flash memory totals
2 Mbytes mapped into two separate asynchronous memory banks,
1 Mbyte each. Secondary Flash memory, along with SRAM and registers,
occupies the third bank of asynchronous memory space. The processor’s
~AMS0
,
~AMS1
, and
~AMS2
memory select pins are used for that purpose.
