23.1.2.2 Copy Base Address Frame
With a Copy Base Address Frame, the two parameters of a Remote Window are
transferred from the transmitting controller to the receiving controller to initialize or to
redirect the Remote Window.
The Copy Base Address Frame contains the following parts:
• Header:
The header starts with frame code FC = 00
B
followed by the pipe number PN of the
pipe targeted by the transmitted base address bits and the size code.
• Remote Window address location:
The 28 most significant bits of the 32-bit base address bits can be programmed by
the transmitting controller (the 4 LSBs are considered as 0). The base address of a
Remote Window has to be aligned to its size, e.g. a window of 1 Kbyte has to start at
1Kbyte address boundaries.
• Remote Window size:
The size is defined by the 4-bit coded buffer size BS. The maximum size is 64 Kbytes.
• Parity bit P
