AD5700-1 HART_OUT connection

I use EVAL-AD5700-1EBZ to connect to RSET of EVAL-AD5422LFEBZ based on the description in the section 'Circuit Evaluation & Test' in the following page.

In the description, the connection is shown as the attached file.

However, EAVL-AD5700-1EBZ itself has C12(22nF) between HART_OUT pin and GND and C14(2.2uF) between HART_OUT pin to HART_OUT borad termial. they are NOT show in the description and CN0278.

How do they work and affect on HART_OUT signal?

Do I need to remove them?
