SPI Flash Memory
The CPU manages access to flash memory from the I-Code and D-Code buses via the built-in SPI
Flash Control Unit (SPIC). At the same time, operations such as erasure, programming, and read-write
protection are also implemented, and the execution of code stored in flash memory is accelerated by
instruction prefetch and cache.
PSRAM
4M bytes PSRAM, using 50MHz DDR memory.
System storage control address allocation
Address allocation is as following table.
