7 Flash Media Controller Programming Model

This section describes the internal PCI configuration registers used to program the PCI6x21/PCI6x11 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 PCI6x21/PCI6x11 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 7−1 illustrates the configuration header that includes both the predefined portion of the configuration

space and the user-definable registers.
