23.1.2.3 Write Offset and Data Frame
A Write Offset and Data Frame is used by the transmitting controller to send an address
offset and data to the receiving controller. This frame is initiated by a write operation to
one of the Transfer Windows in the transmitting controller.
The Write Offset and Data Frame contains the following parts:
• Header:
The header starts with frame code FC = 01
B
followed by the pipe number PN of the
Transfer Window that has been the target of the write operation.
• m-Bits of write offset:
These bits define the write offset. The value of m depends on the size of the Remote
Window, defined by the Copy Base Address Frame (m = 1-16).
• Write data field:
The write data field can be 8-bit, 16-bit, or 32-bit wide, depending on the data width
of the write access to the Transfer Window.
• Parity bit P
