*1 : QnA-compatible 3E frame command
*2 : Set the processing points within the range of the following calculation formula.
(Word access points) x 12 + (Double word access points) x 14 <= 1920
• For bit devices, 1 point is 16 bits for word access and 32 bits for double word access.
• For word devices, 1 point is 1 word for word access and 2 words for double word access.
