在ADC12D1800评估板的原理图中ADC12D1XXX的C6为POREN,C7为WSS,可是芯片Datasheet 中 C6 为V_A,C7为NC,所以问一下大家,为什么?还有POREN和WSS是什么意思,有什么功能?谢谢!

C6 – This pin was used for an internal test function for pre-production silicon, but it is not bonded in
production parts.
• C7 – This pin was used for an internal test function; it is not bonded in production parts and may be
connected to any potential or left floating.
Ball No. ADC1xD1x00 Data Sheet Name Reference Board Connection
C6 VA POREN (from FPGA)
C7 NC WSS (from FPGA)
For a few exceptions, Texas Instruments Reference Board does not follow the datasheet
recommendations for certain pin connections. These exceptions are listed in Table 2. Historically, the
exceptions exist because the Reference Board was developed before silicon development was finalized.
