23.2.1.1 Copy Base Address Frame
A Copy Base Address Frame defines the location and the size of a Remote Window.
Figure 23-20 Copy Base Address Frame Flow
Transmitting Controller
The transmission of a Copy Base Address Frame is started after a transmitter pipe x
base address registers TPxBAR has been written, triggering the following actions for
pipe x.
• Bit field TPxBAR.BS (4-bit coded buffer size) is loaded into bit field TPxSTATR.BS
