SN65DP159: 0x0C寄存器的[1:0]位似乎不可控

Part Number: SN65DP159

参考其它论坛但是仍有疑问:https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1337918/sn65dp159-uncontrollable-issue-with-1-0-bits-of-the-0x0c-register

向DP159写入该字段为01,且应答成功,但是读出为00,是否是因为U硬件自动更新的原因,该如何解决?
0x0C寄存器的[1:0]位似乎不可控,程序中这两位写入 01,读出来是00
已经是在IIC模式下


以下是硬件原理图:
