Exceptions

1. All pins are 5V tolerant except for the pins with PCI (INPCI, OPCI) buffer types.

2. All pins are back-drive protected except for the output pins with PCI (OPCI) buffer types.

3. The following pins are excluded from the requirement of total pins leakage maximum 10

µA: V

SB5, REF5V,

REF5V_STBY, 3V_DDCSCL, 5V_DDCSCL, 3V_DDCSDA, 5V_DDCSDA, SMB1_SCL, SMB1_SDA, SMB2_SCL,

SMB2_SDA.

4. The following pins have an internal static pull-up resistor (when enabled) and therefore may have leakage current from

VSUP (when VIN = 0): LPCPD, ACK, AFD_DSTRB, ERR, INIT, PE, SLIN_ASTRB, STB_WRITE, KBRST, GA20, SIOPME,

GPIOE00-07, GPIOE10-13, PWRGD_PS, CPU_PRESENT, FPRST, PRIMARY_HD, SECONDARY_HD, SCSI.

5. The following pins have an internal static pull-down resistor (when enabled) and therefore may have leakage current to

VSS (when VIN = VSUP): BUSY_WAIT, PE and SLCT.

6. The following strap pins have an internal static pull-up resistor enabled during Power-Up reset and therefore may have

leakage current to VSUP (when VIN = 0): BADDR, TRIS, TEST.

7. When VDD3 = 0V, the following pins present a DC load to VSS of 30 KΩ minimum (not tested, guaranteed by design) for

a pin voltage of 0V to 3.6V: CTS, DCD, DSR, DTR_BOUT, RI, RTS, SIN, SOUT.
