... Philips Semiconductors Advanced modem/audio analog front-end 6.7.3 Control Register Data Transfer The last 16 bits of the UCB1100 word is made up of control register data. The selection of the control register and whether it is read or written is defined by the control register address field [bit 17:20] and the “write” bit [bit 21]. For a read action on the a control register, the control register address field has to set to the desired control register address and the “ ...
