How to output high frequency data in CPL

[Mikasa]

I am using CESM 2.1.3. I have found how to output high frequency data in CAM, CLM and etc in CESM Tutorial. However, there is no information on how to output CPL variables.
As shown in the figure below, I have found some clues on the CESM CPL namelist webpage. I guess the variable names starting with hist control the CPL output data. Is that right ?

Coupler ouput frequency can be adjusted with the XML variables
HIST_OPTION and HIST_N for instantaneous output or
AVGHIST_N and AVGHIST_OPTION for averaged values.

Thanks for your reply. But I wonder what is the difference between the HIST_OPTION value nhours' and 'nhour' ?

The drv namlist webpage shows that

[nhour/s] , history snapshot every history_n nhours , relative to current run start time

Does it mean nhours' is the same as 'nhour' ?

yes they are the same
