Table 1: OXCB950 performance compared with PCI Bridge + generic UART combinations in PCI mode

1.1 Improvements of the OXCB950 over discrete solutions:

Improved access timing:

Access to the internal UART requires zero or one PCI wait states. A cardbus/PCI read transaction from the internal UART can

complete within five PCI clock cycles and a write transaction to the internal UART can complete within four PCI clock cycles.

Reduces interrupt latency:

The OXCB950 offers shadowed FIFO levels and Interrupt status registers of the internal UART, as well as general device

interrupt status, to reduce the device driver interrupt latency.

Power management:

The OXCB950 complies with the Cardbus Power Management Specification, given by the PC CARD standard release 7.0/7.1,

the PCI Power Management Specification 1.0 and the PC98/99 Power Management specifications, by offering the extended
