226 / 253 page  WM8321 Production Data w PD, February 2012, Rev 4.0 226 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R30727 (7807h) Unique ID 8 15:0 UNIQUE_ID [15:0] 0000_0000 _0000_000 0 Unique ID, Word 0 Register 7807h Unique ID 8 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R30736 (7810h) Customer OTP ID 15 OTP_AUTO_P ROG 0 If this bit is set when bootstrap data is loaded from ICE (in development mode), then the ICE contents will be programmed in the OTP. 14:1 OTP_CUST_ID [13:0] 00_0000_0 000_0000 This field is checked when an ‘ON’ transition is requested. A non-zero value is used to confirm valid data. 0 OTP_CUST_FI NAL 0 If OTP_CUST_FINAL is set in the OTP and also set in the DCRW, then no further Writes are possible to the OTP. Register 7810h Customer OTP ID REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R30737 (7811h) DC1 OTP Control 15:13 DC2_ON_SLO T [2:0] 000 DC-DC2 ON Slot select 000 = Do not enable 001 = Enable in Timeslot 1 010 = Enable in Timeslot 2 011 = Enable in Timeslot 3 100 = Enable in Timeslot 4 101 = Enable in Timeslot 5 110 = Controlled by Hardware Enable 1 111 = Controlled by Hardware Enable 2 12:8 DC2_ON_VSE L [6:2] 0_0000 DC-DC2 ON Voltage select DC2_ON_VSEL [6:0] selects the DC-DC2 output voltage from 0.6V to 1.8V in 12.5mV steps. DC2_ON_VSEL [6:2] controls the voltage in 50mV steps. DC2_ON_VSEL [6:0] is coded as follows: 00h to 08h = 0.6V 09h = 0.6125V … 48h = 1.4V (see note) … 67h = 1.7875V 68h to 7Fh = 1.8V Note - Maximum output voltage selection in 4MHz switching mode is 48h (1.4V). 7:5 DC1_ON_SLO T [2:0] 000 DC-DC1 ON Slot select 000 = Do not enable 001 = Enable in Timeslot 1 010 = Enable in Timeslot 2 011 = Enable in Timeslot 3 |
