I cannot understand the below check item.
6.3 Have the 3pF bypass capacitors been added to PTC1-5?
Why PTC1-5 require 3 pF bypass capacitors?
Please reply as soon as possible.

Hello,
Could you please refer to the AN5377 Hardware Design Considerations for MKW41Z/31Z/21Z BLE and IEEE 802.15.4 Device section 6.1.1 for further information about this?

Dear Estephania
Thank you for your reply.
I want to use PTC2 and PTC3 with LPUART0_RX and LPUART0_TX respectively.
Is the 3 pF bypass capacitor necessary also in this case?
Please reply as soon as possible.
Best regards,
Takashima
