DESCRIPTION
HAD31
A8 5V Tol, CMOS, BiDir PCI address/data bus bit 31. These signals make up the multiplexed PCI address and data bus on
the primary interface. During the address phase of a primary bus PCI cycle, HAD31-HAD0 contain a
32-bit address or other destination information. During the data phase, HAD31-HAD0 contain data.
HAD30
A9 5V Tol, CMOS, BiDir PCI address/data bus bit 30.
HAD29
C8 5V Tol, CMOS, BiDir PCI address/data bus bit 29.
HAD28
A10 5V Tol, CMOS, BiDir PCI address/data bus bit 28.
HAD27
B9 5V Tol, CMOS, BiDir PCI address/data bus bit 27.
HAD26
B10 5V Tol, CMOS, BiDir PCI address/data bus bit 26.
HAD25
C9 5V Tol, CMOS, BiDir PCI address/data bus bit 25.
HAD24

HAD5
J15 5V Tol, CMOS, BiDir PCI address/data bus bit 5.
HAD4
J14 5V Tol, CMOS, BiDir PCI address/data bus bit 4.
HAD3
K14 5V Tol, CMOS, BiDir PCI address/data bus bit 3.
HAD2
K15 5V Tol, CMOS, BiDir PCI address/data bus bit 2.
HAD1
L14 5V Tol, CMOS, BiDir PCI address/data bus bit 1.
HAD0
L16 5V Tol, CMOS, BiDir PCI address/data bus bit 0.
HBE3
C10 5V Tol, CMOS, BiDir PCI bus commands and byte enables. These signals are multiplexed on the same PCI terminals.
During the address phase of a primary bus PCI cycle, HBE3-HBE0 define the bus command. During
the data phase, this 4-bit bus is used as byte enables. The byte enables determine which byte paths
of the full 32-bit data bus carry meaningful data. HBE3 applies to byte 3 (HAD31-HAD24).
HBE2
B14 5V Tol, CMOS, BiDir PCI bus commands and byte enables. HBE2 applies to byte 2 (HAD23-HAD16).
HBE1
E16 5V Tol, CMOS, BiDir PCI bus commands and byte enables. HBE1 applies to byte 1 (HAD15-HAD8).
