请问90s8515 的外部SRAM.html">SRAM是如何map的，从0x260还是0x0000开始？
这里是我从网上看到的，各位给个解释，多谢。
“Due to the potentially LONG latencies involved in a CD-ROM access, data must be cached in the external SRAM. Originally, we had planned to use the full 32KB of external SRAM as a buffer. The AVR datasheet made it misleadingly appears as though the external SRAM were mapped into the address space at an address starting immediately above that of the internal RAM. We eventually discovered that the external SRAM is mapped starting at address 0, and that the portion of SRAM that overlaps with the internal RAM lacks a distinct address space.“
