1.7.3.2LDO Control Register [7004h]

When the DSP_LDO is enabled by the DSP_LDO_EN pin [D12], by default, the DSP_LDOO voltage is set to 1.3 V. The DSP_LDOO voltage can be programmed to be either 1.05 V or 1.3 V via the DSP_LDO_V bit (bit 1) in the LDO Control Register (LDOCNTL).

At reset, the USB_LDO is turned off. The USB_LDO can be enabled via the USBLDOEN bit (bit 0) in the LDOCNTL register.

1.7.3.3LDO Control

All three LDOs can be simultaneously disabled via software by writing to either the BG_PD bit or the LDO_PD bit in the RTCPMGT register (see Figure 1-36). When the LDOs are disabled via this mechanism, the only way to re-enable them is by asserting the WAKEUP signal pin (which must also have been previously enabled to allow wakeup), or by a previously enabled and configured RTC alarm, or by cycling power to the CVDDRTC pin.

ANA_LDO: The ANA_LDO is only disabled by the BG_PD and the LDO_PD mechanism described above. Otherwise, it is always enabled.

DSP_LDO: The DSP_LDO can be statically disabled by the DSP_LDO_EN pin. It can be also dynamically disabled via the BG_PD and the LDO_PD mechanism described above. The DSP_LDO can change its output voltage dynamically by software via the DSP_LDO_V bit in the LDOCNTL register (see

Figure 1-37). The DSP_LDO output voltage is set to 1.3 V at reset.

USB_LDO: The USB_LDO can be independently and dynamically enabled or disabled by software via the USB_LDO_EN bit in the LDOCNTL register (see Figure 1-37). The USB _LDO is disabled at reset.

Table 1-47shows the ON/OFF control of each LDO and its register control bit configurations.
