我的理解：关于RM48 RAM 有两种一种是on-chip sram 一种是TC RAM。对于on-chip sram 只有PBIST诊断，对于TC RAM只有ECC？？？ 但是我RM48文档手册P110 看到如下：
The microcontrollers also support a hardware-based auto-initialization of on-chip SRAM modules. This process also takes into account the read protection scheme implemented for each SRAM module – ECC or parity.。
这句话是说on-chip sram也实现了ECC保护？？？？？？？？？？ 谢谢！！！！！
