ISL3874 Signal Descriptions
TABLE 1. HOST INTERFACE PINS
PIN NAME
PIN
NUMBER
PIN I/O TYPE
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
A11
5V Tol, CMOS, BiDir PCI address/data bus bit 24.
HAD23
B11
5V Tol, CMOS, BiDir PCI address/data bus bit 23.
HAD22
B12
5V Tol, CMOS, BiDir PCI address/data bus bit 22.
HAD21
A12
5V Tol, CMOS, BiDir PCI address/data bus bit 21.
HAD20
A13
5V Tol, CMOS, BiDir PCI address/data bus bit 20.
HAD19
C12
5V Tol, CMOS, BiDir PCI address/data bus bit 19.
HAD18
A14
5V Tol, CMOS, BiDir PCI address/data bus bit 18.
HAD17
C13
5V Tol, CMOS, BiDir PCI address/data bus bit 17.
HAD16
C14
5V Tol, CMOS, BiDir PCI address/data bus bit 16.
HAD15
E14
5V Tol, CMOS, BiDir PCI address/data bus bit 15.
HAD14
E15
5V Tol, CMOS, BiDir PCI address/data bus bit 14.
HAD13
F16
5V Tol, CMOS, BiDir PCI address/data bus bit 13.
HAD12
F15
5V Tol, CMOS, BiDir PCI address/data bus bit 12.
HAD11
F14
5V Tol, CMOS, BiDir PCI address/data bus bit 11.
HAD10
G16
5V Tol, CMOS, BiDir PCI address/data bus bit 10.
HAD9
G15
5V Tol, CMOS, BiDir PCI address/data bus bit 9.
HAD8
G14
5V Tol, CMOS, BiDir PCI address/data bus bit 8.
HAD7
H15
5V Tol, CMOS, BiDir PCI address/data bus bit 7.
HAD6
G13
5V Tol, CMOS, BiDir PCI address/data bus bit 6.
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).
