The lock bit enables and disables the writing of the TIACN and the REFCN registers. In order to change the
content of the TIACN and the REFCN registers the lock bit needs to be set to “0”.
Bit Name Function
[7:1] RESERVED Write protection
0 LOCK 0 Registers 0x10, 0x11 in write mode
0 LOCK 1 Registers 0x10, 0x11 in read only mode (default)
TIACN REFCN 寄存器配置好了，然后锁定好。断电，再上电 TIACN REFCN 上次配置的值还在不啊？？？
