80 / 291 page  WM8310 Pre-Production w PP, May 2012, Rev 3.1 80 ADDRESS BIT LABEL DEFAULT DESCRIPTION 1:0 DC3_ON_VS EL [1:0] 00 DC3_ON_VSEL[6:0] selects the DC- DC3 output voltage from 0.85V to 3.4V in 25mV steps. DC3_ON_VSEL[6:2] also exist in ICE/OTP memory, controlling the voltage in 100mV steps. DC3_ON_VSEL[6:0] is coded as follows: 00h = 0.85V 01h = 0.875V … 65h = 3.375V 66h to 7Fh = 3.4V R16483 (4063h) DC3 SLEEP Control 15:13 DC3_SLP_S LOT [2:0] 000 Same as DC-DC1 9:8 DC3_SLP_M ODE [1:0] 00 Same as DC-DC1 6:0 DC3_SLP_V SEL [6:0] 000_0000 DC-DC3 SLEEP Voltage select 0.85V to 3.4V in 25mV steps 00h = 0.85V 01h = 0.875V … 65h = 3.375V 66h to 7Fh = 3.4V Table 36 DC-DC (Buck) Converter Control 15.12.3 DC-DC BOOST CONVERTER CONTROL The register controls for configuring the DC-DC4 boost converter are defined in Table 37. Note that the DC4_RANGE control register is locked by the WM8310 User Key. This register can only be changed by writing the appropriate code to the Security register, as described in Section 12.4 for further details. ADDRESS BIT LABEL DEFAULT DESCRIPTION R16484 (4064h) DC4 Control 15:14 DC4_ERR_A CT [1:0] 00 DC-DC4 Error Action (Undervoltage) 00 = Ignore 01 = Shut down converter 10 = Shut down system (Device Reset) 11 = Reserved Note that an Interrupt is always raised. 12:11 DC4_HWC_ SRC[1:0] 00 DC-DC4 Hardware Control Source 00 = Disabled 01 = Hardware Control 1 10 = Hardware Control 2 11 = Hardware Control 1 or 2 8 DC4_HWC_ MODE 1 DC-DC4 Hardware Control Operating Mode 0 = DC-DC4 is controlled by DC4_ENA 1 = DC-DC4 is disabled when Hardware Control Source is asserted |
