MCT8316A: 无法固化参数到EEPROM

Part Number: MCT8316A
Other Parts Discussed in Thread: MCF8316A

按照手册说明进行操作

Write 0x80000000 into register 0x0000E6 to write the shadow register (0x000080-0x0000AE) values into the EEPROM.

但是写了0x80000000到0xE6寄存器之后,重新上电读出来的参数还是默认参数,之前修改的参数并没有固化到EEPROM

看了0xE6寄存器的位定义,发现还需要写EEPROM_WRITE_ACCESS_KEY这8位,来解锁写EEPROM指令

请问MCT8316A的   【EEPROM_WRITE_ACCESS_KEY】这个值应该是写多少,我看MCF8316A是5A
