224 / 253 page  WM8321 Production Data w PD, February 2012, Rev 4.0 224 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R16528 (4090h) Clock Control 1 15 CLKOUT_ENA 0 CLKOUT output enable 0 = Disabled 1 = Enabled Protected by security key. 13 CLKOUT_OD 0 CLKOUT pin configuration 0 = CMOS 1 = Open Drain 10:8 CLKOUT_SLO T [2:0] 000 CLKOUT output enable 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 = Do not enable 111 = Do not enable 6:4 CLKOUT_SLP SLOT [2:0] 000 CLKOUT output SLEEP slot select 000 = Controlled by CLKOUT_ENA 001 = Disable in Timeslot 5 010 = Disable in Timeslot 4 011 = Disable in Timeslot 3 100 = Disable in Timeslot 2 101 = Disable in Timeslot 1 110 = Controlled by CLKOUT_ENA 111 = Controlled by CLKOUT_ENA Register 4090h Clock Control 1 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION REFER TO R16529 (4091h) Clock Control 2 15 XTAL_INH 0 Crystal Start-Up Inhibit 0 = Disabled 1 = Enabled When XTAL_INH=0, the internal RC oscillator will provide CLKOUT until the crystal oscillator is valid. When XTAL_INH=1, the ‘ON’ transition is inhibited until the crystal oscillator is valid. 13 XTAL_ENA 0 Crystal Oscillator Enable 0 = Disabled at all times 1 = Enabled in OFF, ON, SLEEP states (Note that the BACKUP behaviour is determined by XTAL_BKUPENA.) This field can only be written to by loading configuration settings from OTP/ICE. In all other cases, this field is Read Only. 12 XTAL_BKUPE NA 1 Selects the RTC and 32.768kHz oscillator in BACKUP state 0 = RTC unclocked in BACKUP 1 = RTC maintained in BACKUP (Note that XTAL_ENA must also be set if the RTC is to be maintained in BACKUP) Register 4091h Clock Control 2 |
