Hello Team

Could you check my question of pin control for SWD?
Target MCU is KEA8.
As my checking on the RM, SWD_CLK is required the pull-down like following.
However, in case of normal EVK for KEA, it does not connect with the external pull-down.

Questions are;
1. Is the external pull-down” mandatory or option?
2. If it has to connect, could you let me know the pull down resistor value?

thank you.
