还有部分工程是没有在工程定义真正大小的,也就是芯片本身没有keil开发包,用其他芯片或通用开发包定义的工程。 在keil上是没有定义对应芯片型号或用了其他芯片的定义的8051这就会导致显示占用的最大值错误。 要确保工程文件里面的IRAM,XRAM,IROM都是正确的才行。
The TP0456 uses almost the same static cell structure as the earlier CMOS chips, but the layout was changed slightly. In particular, the select line runs between the two inverter lines, rather than on the side. I don't know why they made this change, as it doesn't appear to change th...
The MSP430 memory structure. Diagram courtesy of Texas Instruments. Code memory, AKA program memory or read-only memory (ROM), is where the program’s instructions are stored. We also call this “the flash” because nowadays code memory is implemented using a nonvolatile storage tec...
