Displaying the high word 16-bit for the read data.(D31~D16)
The above table indicates the address for 16-bit data bus. In 8-bit data bus access, the 16bit data bus are divided into the high word byte (D15~8) and the low word by
te (D7~0) by using address signal A3~A0.
Each axis has RR1,RR2 and RR3 (status register 1,2 and 3). It can be read the data in these registers by the same address. It depends on the axis assignment of the
last command to read the data in the mode register of which axis. Or, user can select the axis by writing the NOP command which is assigned an axis just before.
