11 Flash Media Controller Programming Model

This section describes the internal PCI configuration registers used to program the PCI7x21/PCI7x11 flash media controller interface. All registers are detailed in the same format: a brief description for each register is followed by the register offset and a bit table describing the reset state for each register.

A bit description table, typically included when the register contains bits of more than one type or purpose, indicates bit field names, a detailed field description, and field access tags which appear in the type column. Table 4−1 describes the field access tags.

The PCI7x21/PCI7x11 controller is a multifunction PCI device. The flash media controller core is integrated as PCI function 3. The function 3 configuration header is compliant with the PCI Local Bus Specification as a standard header. Table 11−1 illustrates the configuration header that includes both the predefined portion of the configuration space and the user-definable registers.
