If byte 8, bit 4 of the EEPROM is set to ‘0’, the ATA interface pins are only active when VBUS_ATA_EN is asserted. See section 5.3.9.
A ‘#’ sign after the pin name indicates that it is active LOW.
The General Purpose inputs can be enabled on ATAPUEN, PWR500#, and DRVPWRVLD via EEPROM byte 8, bit 7 on CY7C68320/CY7C68321.
