31 / 52 page  CS4298 DS315PP2 31 6.1.22 Extended Modem ID (Index 3Eh) PRH Handset DAC. When set powers down the Handset DAC. PRG Handset ADC. When set powers down the Handset ADC. PRF Line 2 DAC. When set powers down the Line 2 DAC. PRE Line 2 ADC. When set powers down the Line 2 ADC. PRD Line 1 DAC. When set powers down the Line 1 DAC. PRC Line 1 ADC. When set powers down the Line 1 ADC. PRB Modem Reference. When set powers down the modem reference. The modem and audio share a com- mon reference. The reference will not power down unless PR3 of the Power Down Ctrl/Stat (Index 26h) register is also set. PRA GPIO. When set the GPIO pins are tri-state and powered down. Slot 12 is marked invalid if the AC-link is active. HDAC Handset DAC. When set indicates the Handset DAC is ready. HADC Handset ADC. When set indicates the Handset ADC is ready. DAC2 Line 2 DAC. When set indicates the Line 2 DAC is ready. ADC2 Line 2 ADC. When set indicates the Line 2 ADC is ready. DAC1 Line 1 DAC. When set indicates the Line 1 DAC is ready. ADC1 Line 1 ADC. When set indicates the Line 1 ADC is ready. MREF Modem Reference. When set indicates the modem reference is ready. GPIO GPIO. When set the GPIO pins are ready. Slot 12 is marked valid. Default Mode 0 x0CFh Mode 1 x03Fh Mode 2 x08Fh Mode 3 x047h Where x is determined by the state of ID[1:0] input pins. PR[A:H] are read/write bits that provide power management of the modem AFE subsection. All re- maining bits are read/only status indicating modem subsystems are ready for operation. After reset or issuing a change to the MD[1:0] of AC Mode (Index 5Eh) register, the respective status bits for that mode will be clear until the subsystem becomes ready. 6.1.23 Line 1 DAC/ADC Rate (Index 40h) SR[15:0] Line 1 DAC/ADC Sample Rate. Default Read-only value BB80h, indicating 48 kHz sample rate. 6.1.24 Line 2 DAC/ADC Rate (Index 42h) SR[15:0] Line 2 DAC/ADC Sample Rate. Default Read-only value BB80h, indicating 48 kHz sample rate.
