Sets the VDD_TMPR_CSI domain to VCC_IO_3V3_1V8
J9
Sets VDD_USDHC1_VSELECT Domain
0 Ohm
1+2
Sets the VDD_USDHC1_VSELECT domain to 1.8V
2+3
Sets the VDD_USDHC1_VSELECT domain to 3.3V
J10
Sets VDD_EMMC0 Domain
0 Ohm

J11
Connects VSELECT pin on the PMIC (U1) to a signal or ground. VSELECT sets the voltage
of VCC_LDO_SD1 on the PMIC, which in turns goes to the connector and sets the voltage of
the following signals:
X_USDHC1_CLK, X_USDHC1_CMD/NAND_CE0_B, X_USDHC1_DATA0/NAND_CE1_B,
X_USDHC1_DATA1/NAND_RE_B, X_USDHC1_DATA2/NAND_WE_B,
X_USDHC1_DATA3/NAND_ALE
0 Ohm
1+2
Connect VSELECT to X_USDHC1_VSELECT/NAND_RE_P
2+3
Connect VSELECT to ground
J12
Connects LDO2EN pin on the PMIC (U1) to a signal or ground. LDO2EN
enables VCC_LDO_SD1.
0 Ohm

Connect LDO2EN to X_USDHC1_RESET_B/NAND_RE_N
2+3
Connect LDO2EN to ground
