MPL3115A2 register INT_SOURCE

I’m trying to understand a little about the MPL3115A2 pressure sensor we are using.

 

Section 13.11, INT_SOURCE (0x12), second paragraph: “The setting of the bits is rising edge sensitive, the bit is set by a low to high state change and reset by reading the appropriate source register”.

 

What does this mean for the SRC_PW and SRC_TW bits, i.e., what is the source? Does this mean to reading this register (INT_SOURCE) will clear these bits, or must I read another “source” register?
