2.9 Reset Configuration
The GT-32090 must acquire some knowledge of the sys-
tem before it is configured by the software. The following
configuration pins are sampled from when Rst* is
asserted, until 4 Clock cycles after it is deasserted:
DMAAck[2:0]* - Indicates the three MSB’s of the GT-
32090 Internal address space decode, bits 31:29. These
bits are sampled into the Internal Address Space Decode
& Control register bits [5:3].
DMAReq[2:0] - Indicates the three MSB’s of the GT-
32090’s four devices address, bits 31:29. These bits are
sampled into bits [6:4] of the Device n Address Space
registers.
