IBM Packet Routing Switch Serial Interface Converter
2.1.12 Protocol Engine (PE) Egress Interface
The converter connects to the PE’s 32-bit bus via the PE egress interface. Egress transmit framing controls
data and idle packet transfer. The PE’s egress interface monitors the behavior of TXFULL, controls TXENB
accordingly, and generates the Start of Packet to the PE. A parity bit covering the 32-bit word can be gener-
ated according to a dedicated bit in the configuration table registers.
