Figure 5. Flash Buffer Write Cycle
Write Accesses: The CPU, as the initiator, drives the address lines AD[31:0], the command and
byte enable lines C/BE#[3:0] and the control lines IRDY# and FRAME#. It also provides the
82551ER with valid data immediately after asserting IRDY#. The 82551ER controls the TRDY#
signal and de-asserts it for a certain number of clocks until valid data is written to the Flash buffer.
By asserting TRDY#, the 82551ER signals the CPU that the current data access has completed.
Flash buffer write accesses can be byte length only.
