Secondary Bitstream
Interface
This chapter describes the secondary bitstream interface and contains
the following sections:
•
•
•
Section 9.3, “FRAME Pin Transfers”
•
Section 9.4, “FIFO and Buffer Operation”
•
Section 9.5, “Secondary Bitstream Interface Registers”
As a separate bitstream port, the secondary bitstream interface is a
synchronous, flow-controlled 8-bit data port. The secondary bitstream
port pins are shared with the ATAPI interface pins. As a result, the
secondary bitstream port is only available when the storage port is in SD
mode. Transfers are clocked from the rising edge of SBP_CLK. The
direction of the port is controlled by the BSRD bit in the Secondary
Bitstream Configuration register. (See
