P200 Host Interface Specification Introduction
This section describes functionality P200 from host's perspective. services provided allow host processor optimally implement network application, relying P200 real-time network processing. P200 system information loaded host processor following description. downloaded information volatile must reloaded event power failure. Following verification P200 initialization (see Initialization Flow) system information (Layer_Config_Info) written P200 through "write transaction" Layer_Mgmt_Write command (see Write Transaction Flow). host transmit packets (Packet) using "write transaction" Packet_Transmit command. Completion packet transmission notification receipt packet through "attention sequence" (see Attention Sequence Flow) after which host must determine reason attention through "read transaction" Interface_Read command (see Read Transaction Flow). Packets retrieved through "read transaction" Packet_Receive command. Details various data structures, commands command protocol indicated below.
