在MC33771C的INIT寄存器中有2个位的解释在NXP的两份文档中对TPL_TX_Term的解释不一致，请问以哪一个为准？
1.Rev. 3.0 — 11 July 2019的datasheet中，描述如下：

这个理解为一个解释吧！文档没有！
@guoweisun 你提供的这部分说明是在哪个文档中体现的？我这版datasheet没有找到
Hi ZDDL
以datasheet 为准：
看下面的用法：
"RDTX_IN" and "RDTX_OUT" are both corresponding to one TPL line (input/output) on the IC.
Even though they are called IN and OUT, they are both symmetrical.
Only one of the two TPL_TX_Term (RDTX_IN or RDTX_OUT) should be set to 1 in the case of a single ended daisy chain. The one set to 1 should be the TPL line that is not used.
This way, if the last node is connected to the chain through the RDTX_IN line, then TPL_TX_Term (RDTX_OUT) should be set to 1 and vice-versa.
Also note that in case of double-ended chain (also called loopback), neither TPL_TX_Term should be 1.
