I known, due to my poor English, I do not understand that section correctly. after reading the whole chapter, I understand. the Global Pin Control Low / High Register can update lower 16bit of 32 PCRs (PORT_PCR[0-31])  with the same value. the higher 16 bit of Global Pin Control Low / High Register select which PCRs are updated. the value in the lower 16 bit of Global Pin Control Low / High Register are updated to the lower 16bits of the selcted PCRs.  in the similar way, Global Interrupt Control Low /High Register update the higher 16bits of the PCRs.
