Altera Dual Configuration IP Core - Max10

I have a question on the Dual Configuration IP Core documentation that I downloaded from Altera

https://www.altera.com/en_us/pdfs/literature/hb/max-10/ug_m10_config.pdf

Table 5-1 , entry row 3

Offset: 2 ; R/W : W ; Width : 32 ; Description - Bit 0 - Trigger read operation from the user watchdog , Bit 1- Trigger read operation from .....

It seems the result bit 0 operation is stored at this location

offset 4 : R/W : R ; Width: 32 ; Description - Bit 11:0 user watchdog value , bit 12 - current state of the user watch dog , bit 16:13 - mcm_cs value of current state , bit 31:17 reserved

Questions

1) Is my assumption that operation initiated by Bit 0 in offset 2 resulting in update to offset 4 value correct?

2) Does the value at offset updated continuously as long as bit 0 in offset 2 set to '1' or it is just one time update.

Thanks
