68 / 81 page  WM9090 Production Data w PD, November 2010, Rev 4.1 68 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R74 (4Ah) Write Sequencer 4 0 WSEQ_BUSY 0 Sequencer Busy flag (Read Only). 0 = Sequencer idle 1 = Sequencer busy Note: it is not possible to write to control registers via the control interface while the Sequencer is Busy. Register 4Ah Write Sequencer 4 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R75 (4Bh) Write Sequencer 5 5:0 WSEQ_CURR ENT_INDEX [5:0] 00_0000 Sequence Current Index. This is the location of the most recently accessed command in the write sequencer memory. Register 4Bh Write Sequencer 5 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R76 (4Ch) Charge Pump 1 15 CP_ENA 0 Charge Pump Control 0 = Disabled 1 = Enabled Register 4Ch Charge Pump 1 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R84 (54h) DC Servo 0 13 DCS_TRIG_SI NGLE_1 0 Writing 1 to this bit selects a single DC offset correction for HPOUT1R. In readback, a value of 1 indicates that the DC Servo single correction is in progress. 12 DCS_TRIG_SI NGLE_0 0 Writing 1 to this bit selects a single DC offset correction for HPOUT1L. In readback, a value of 1 indicates that the DC Servo single correction is in progress. 9 DCS_TRIG_SE RIES_1 0 Writing 1 to this bit selects a series of DC offset corrections for HPOUT1R. In readback, a value of 1 indicates that the DC Servo DAC Write correction is in progress. 8 DCS_TRIG_SE RIES_0 0 Writing 1 to this bit selects a series of DC offset corrections for HPOUT1L. In readback, a value of 1 indicates that the DC Servo DAC Write correction is in progress. 5 DCS_TRIG_ST ARTUP_1 0 Writing 1 to this bit selects Start-Up DC Servo mode for HPOUT1R. In readback, a value of 1 indicates that the DC Servo Start-Up correction is in progress. 4 DCS_TRIG_ST ARTUP_0 0 Writing 1 to this bit selects Start-Up DC Servo mode for HPOUT1L. In readback, a value of 1 indicates that the DC Servo Start-Up correction is in progress. 3 DCS_TRIG_DA C_WR_1 0 Writing 1 to this bit selects DAC Write DC Servo mode for HPOUT1R. In readback, a value of 1 indicates that the DC Servo DAC Write correction is in progress. |
