Display Register - Halfword or Word? in forum Newbie Help Zone

I was following Tonc and noticed it defines the display register like this:
#define REG_DISPCNT *((volatile u32*)(MEM_IO+0x0000))

But the documentation I've seen online describes it as a 16-bit register.
Can anyone explain the discrepancy and recommend how I should handle it in my own projects?
