为了使五端口波导网络能较好地工作于六端口反射计中，要求各端口反射系数的绝对值小于0.1。

For the five-port waveguide junction properly works in a six-port reflectometer, the absolute value of the reflection coefficient of every port must be less than 0.1.

上拉寄存器是控制对应端口上拉使能的。

The port pull-up register controls the pull-up resister enable/disable of each port group.
