32 kHz crystal oscillator configuration register
| XTAL32K_WDT_EN | Set this bit to enable the 32 kHz crystal watchdog. |
| XTAL32K_WDT_CLK_FO | Set this bit to FPU the 32 kHz crystal watchdog clock. |
| XTAL32K_WDT_RESET | Set this bit to reset the 32 kHz crystal watchdog by SW. |
| XTAL32K_EXT_CLK_FO | Set this bit to FPU the external clock of 32 kHz crystal. |
| XTAL32K_AUTO_BACKUP | Set this bit to switch to the backup clock when the 32 kHz crystal is dead. |
| XTAL32K_AUTO_RESTART | Set this bit to restart the 32 kHz crystal automatically when the 32 kHz crystal is dead. |
| XTAL32K_AUTO_RETURN | Set this bit to switch back to 32 kHz crystal when the 32 kHz crystal is restarted. |
| XTAL32K_XPD_FORCE | Set 1 to allow the software to FPD the 32 kHz crystal. Set 0 to allow the FSM to FPD the 32 kHz crystal. (R/W) |
| ENCKINIT_XTAL_32K | Applies an internal clock to help the 32 kHz crystal to start. |
| DBUF_XTAL_32K | 0: single-end buffer 1: differential buffer |
| DGM_XTAL_32K | xtal_32k gm control |
| DRES_XTAL_32K | DRES_XTAL_32K |
| XPD_XTAL_32K | XPD_XTAL_32K |
| DAC_XTAL_32K | DAC_XTAL_32K |
| WDT_STATE | Stores the status of the 32 kHz watchdog. |
| XTAL32K_GPIO_SEL | Selects the 32 kHz crystal clock. 0: selects the external 32 kHz clock. 1: selects clock from the RTC GPIO X32P_C. |
| XTL_EXT_CTR_LV | 0: powers down XTAL at high level 1: powers down XTAL at low level |
| XTL_EXT_CTR_EN | Enables the GPIO to power down the crystal oscillator. |
