FSMC_NAND_PCC_TimingTypeDef::HiZSetupTime field
Defines the number of HCLK clock cycles during which the data bus is kept in HiZ after the start of a NAND-Flash write access to common/Attribute or I/O memory space (depending on the memory space timing to be configured). This parameter can be a number between Min_Data = 0 and Max_Data = 254
