23.1.2.8 Answer Frame
An Answer Frame is used by the Remote Controller to send 8-bit, 16-bit, or 32-bit wide
data to the Local Controller. The Answer Frame is the only frame that is transmitted
within a logic Local/Remote Controller assignment from the Remote Controller to the
Local Controller. It is the answer to a Discrete Read Frame or an Optimized Read Frame
that has been sent by the Local Controller to request data from the Remote Controller.
The Answer Frame contains the following parts:
• Header:
The header starts with frame code FC = 10
B
followed by the pipe number PN. The
value of PN is taken from the Read Frame that has triggered the Answer Frame.
• Read data field:
The read data field can be 8-bit, 16-bit, or 32-bit wide, depending on the data width
requested by the Read Frame that triggered the Answer Frame.
• Parity bit P
