(1) LPDS state: The state of unused I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(2) Hibernate mode: The state of the I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(3) To minimize leakage in some serial flash vendors during LPDS, TI recommends that the user application always enables internal weak pulldowns on FLASH_SPI_DIN,
FLASH_SPI_DOUT, and FLASH_SPI_CLK pins.
