8 / 121 page  DS-0019 Jun 05 External—Free Release Page 8 OXmPCI954 OXFORD SEMICONDUCTOR LTD. 2 OXMPCI954 DEVICE MODES The OXmPCI954 supports several modes of operation. 3 modes of the device are (software) backwards compatible with the OX16PCI954 device. There are a further 3 modes that are enhanced modes, which offer additional features over those available in the backwards compatible modes. Then, there is a standalone mode that allows a synchronous local bus access to the internal UARTs, without any form of PCI transactions. These modes are summarized in the following table. Device Mode Mode Pin Selection Functionality Backwards Compatible / Enhanced Modes 000 MODE(2:0) = 000 Function 0 : QUAD Uarts Function 1 : 8-bit Local Bus Backwards Compatible* 001 MODE(2:0) = 001 Function 0 : QUAD Uarts Function 1 : Parallel Port Backwards Compatible* 010 MODE(2:0) = 010 Function 0 : QUAD Uarts Subsys ID/Subsys Vendor ID via Device Pins Backwards Compatible* 011 MODE(2:0) = 011 Function 0 : QUAD Uarts (Unique BARs) Function 1 : 8-bit Local Bus Enhanced Mode 100 MODE(2:0) = 100 Function 0 : QUAD Uarts Function 1 : 8-bit Local Bus Enhanced Mode 101 MODE(2:0) = 101 Function 0 : QUAD Uarts Function 1 : Parallel Port Enhanced Mode 110 MODE(2:0) = 110 TestMode (Reserved). N/A 111 MODE(2:0) = 111 Standalone Mode N/A * The OXmPCI954 is not a direct ‘drop-in’ replacement part for the OX16PCI954 owing to a small pinout change and voltage. The device is only S/W compatible. In the Enhanced Modes, the following additional features are made available over the underlying functionality of the device. • Pin 88/M15 (MIO[11]) is re-defined as a PCI/miniPCI Mode Selection Pin. Functionality normally associated with the pin MIO[11] is no longer available. This results in the pins MIO[10:0] serving as Multi-purpose I/O pins. • All Function 0 and Function 1 interrupts assert on the INTA# pin (by default). • Local Registers provide additional Controls and Status Indication. • Function 0 option to allow each UART to be separately addressable via its own Base Address Register (in I/O Space) This option can be exercised by the device pins (MODE 011) or by using the external EEPROM to set a specified field in the local registers. • Function 0 and Function 1 Power Management Registers indicate Compatibility to Power Management Specification 1.1 • Each function implements Power Management Data/Data Scale fields, returning user defined data. • Availability of 2 Additional EEPROM Zones : The Power Management Data Zone and The Function Access Zone. Specifically for MiniPCI Selection (Pin 88/M15 = ‘1’ in Enhanced Modes) • Device pin INTB#’ is re-defined as a CLKRUN# pin. Compliant to PCI Mobile Design Guide revision 1.1 For PCI modes (Pin 88/M15 = ‘0’ in Enhanced Modes) INTB# is an unused PCI interrupt line. • Device supports PME# generation from the D3cold state and preserves PME# context. This is compliant to Mini PCI Specification, revision 1.0 |
