54 / 114 page  LSPM Left DSP Serial Port Mute. When set to 1, the Left DSP Serial Port input (SDIN) to the digital mixer is muted. Right DSP Serial Port Volume (X9) Default = 0x000000 D7 D6 D5 D4 D3 D2 D1 D0 RSPM res RSPA5 RSPA4 RSPA3 RSPA2 RSPA1 RSPA0 RSPA4-RSPA0 Right DSP Serial Port Attenuation. The least significant bit represents 1.5 dB, with 000000 = 0 dB. See Table 6. res Reserved. Must write 0. Could read as 0 or 1. RSPM Right DSP Serial Port Mute. When set to 1, the Right DSP Serial Port input (SDIN) to the digital mixer is muted. Right Loopback Monitor Volume (X10) Default = 0x111111 D7 D6 D5 D4 D3 D2 D1 D0 SLBE res RLBA5 RLBA4 RLBA3 RLBA2 RLBA1 RLBA0 RLBA5-RLBA0 Right Channel Loopback Attenuation. These bits determine the attenuation of the loopback from the right ADC to the right digital mixer. LBE in I13 must be set to enable loopback. The least significant bit represents -1.5 dB, with 000000 = 0 dB. See Table 6. res Reserved. Must write 0. Could read as 0 or 1. SLBE Stereo LoopBack Enable. When set to 1, control over the Left and Right loopback volume is separated. RLBA5-RLBA0 (X10) control the Right channel, and LBA5-LBA0 (I13) control the Left channel. When set to 0, LBA5-LBA0 (I13) con- trol both channels. DAC Mute and IFSE Enable (X11) Default = 110xxxxx D7 D6 D5 D4 D3 D2 D1 D0 LDMIM RDMIM IFSE res res res res res res Reserved. Must write 0. Could read as 0 or 1. IFSE Independent Sample Freq. Enable. When set to 1, the extended registers X12 and X13 are used to set the sample rate, and registers I8, I10 (OSM1,0), and I22 are ignored. X12 and X13 cannot be modified un- less this bit is set to 1. RDMIM Right Digital Master Input Mixer Mute. When set to 1, the output from the Right DAC is Muted to the Right in- put mixer. See Figure 4. LDMIM Left Digital Master Input Mixer Mute. When set to 1, the output from the Left DAC is Muted to the Left input mixer. See Figure 4. Independent ADC Fs (X12) Default = xxxxxxxx D7 D6 D5 D4 D3 D2 D1 D0 SRAD7 SRAD6 SRAD5 SRAD4 SRAD3 SRAD2 SRAD1 SRAD0 SRAD7-SRAD0 Sample Rate frequency select for the A/D converter. This register is only in effect (and can only be writ- ten) while IFSE=1 in X11. See Table 14.
