(6) VDD_AEMIF2_18_33: can be used as a power supply for EM_A[0:2], EM_CE[1], EM_WE, EM_OE, EM_WAIT, EM_D[0:7] pins, HPI, Keyscan, or GPIO pins. (7) Example 1: VDD_AEMIF2_18_33 at 1.8-V for 8-bit NAND VDD_AEMIF1_18_33 at 3.3-V for GPIO. Example 2: VDD_AEMIF1_18_33 and VDD_AEMIF2_18_33 at 1.8-V for 16-bit NAND. (8) VDD_ISIF_18_33: can be used as a power supply for VPFE pins (CIN[7:0], YIN[7:0], C_WE_FIELD, PCLK), or SPI3 (SPI3_SCLK,SPI3_SIMO,SPI3_SCS[0], SPI3_SCS[1]) or USBDRVVBUS or GPIO pins. (9) See Section 6.12.2.4. Also, resistors should be E-96 spec line (3 digits with 1% accuracy). (10) For proper device operation, this pin must be connected to a 0.22 μF capacitor to VDDA12LDO_USB.
