Voltage Select pin (VSEL_SD/VSEL_DDR)

The function of this pin is configured by VSEL_DDR_SD in MFP_1_CONFIG.

When configured as VSEL_SD, the bit VSEL_RAIL in MFP_1_CONFIG register selects LDO1 or LDO2 to be controlled by the pin. The configuration must not change after power-up.

VSEL_SD/VSEL_DDR configured as 'VSEL_SD': SD-card-IO-select:

The polarity of this pin can be configured by writing to VSEL_SD_POLARITY in MFP_1_CONFIG register. Toggling the pin changes the output voltage of the selected LDO between hard-coded 1.8 V and the voltage configured in LDOx_VOUT. For the SD-card-IO-supply, LDOx_VOUT must be configured for 3.3 V. A change of the VSEL_SD status does not cause a state-transition.

CAUTION: In SD-card-configuration, customer must configure the pin-polarity and drive the pin so that the LDO delivers 3.3 V at start-up.

VSEL_SD/VSEL_DDR configured as 'VSEL_DDR':

Pulling this pin high sets the output voltage of Buck3 to 1.35 V (DDR3LV), leaving the pin floating sets the output voltage of Buck3 to 1.2 V (DDR4, LP-DDR3, some LP-DDR2), pulling the pin low sets the output voltage of the Buck3 voltage configured in BUCK3_VOUT. For LP-DDR4, BUCK3_VOUT must be configured to 1.1 V.

CAUTION: This function needs to be hard-wired and must not change during operation.
CAUTION: The VSEL_RAIL still needs to be configured for the LDO that supplies the SD-card-IO-voltage, as an I2C-command toggles the selected LDO-rail for the SD-card. The VSEL_SD_POLARITY bit has no effect if the pin is configured as VSEL_DDR.

The Table below shows the various combinations.
