Table 1. CS4610/11 PCI Interface Transaction Summary
The PCI bus transactions supported by the
CS4610/11 device are summarized in Table 1. Note
that no Target Abort conditions are signalled by the
device. Byte, Word, and Doubleword transfers are
supported for Configuration Space accesses. Only
Doubleword transfers are supported for Register or
Memory area accesses. Bursting is not supported
for host-initiated transfers to/from the CS4610/11
internal register space, RAM memory space, or
PCI configuration space (disconnect after first
phase of transaction is completed).
