The PWT memory is 16-bits. With reference to the datasheet:
On page 38 Figure 11 shows 16-bit memory read, but no memory write.
On page 39 both 24-bit memory read and write are shown.
On page 49 (Memory Register Map) the second bullet point states: "All the data are 3 bytes long."
My question is:
Is there a 16-bit memory write to access the PWT memory? If so, presumably the second bullet point on page 49 is wrong and needs to be updated.
