Destination parameter in R_USB_READ function

Hello,

I'm developing a project for sending data from Host(PC) to my development kit using "usb_pcdc_with_freertos". I have one question regarding the Destionation Paramater value of R_USB_READ function (Reference RA Flexible Software Package Documentation). 

R_USB_Read (usb_ctrl_t * const p_api_ctrl, uint8_t * p_buf, uint32_t size, uint8_t destination)

(Screenshot from the Function description)

I would like to know which value I have to set to destionation if im using a USB PCDC. Currently, I'm setting destination as USB_CLASS_PCDC. Is it that correct? 

Thank you in advanced!
