5.1.2 Mode Register 1 (Mode-REG1, writable):

Some control bits must be changed during operation. These control bits are combined in Mode-Register 1 and can be set independently of each other (Mode_Reg_S) or can be deleted independently of each other (Mode_Reg_R). Various addresses are used for setting and deleting. Log ‘1’ must be written to the bit position to be set or deleted.
