The Modular Peripheral Sideband Tunneling Interface (M-PESTI) IP core provides early peripheral presence detection and attribute collection before system boot up. This IP core supports bidirectional communication with initiator command and target response structure.

Resource Utilization details are available in the IP Core User Guide.

Features

  • Communicates via half-duplex bidirectional UART protocol at 250k baud rate, 8-bit data, 1-bit odd parity, 1 start bit and 1 stop bit M-PESTI port.
  • Supports Static Discovery payload with CRC-8 payload checksum.
  • Supports one initiator to many targets system.
  • Supports configurable number of M-PESTI devices up to 64 targets.
  • Supports autonomous Static Discovery Payload request command to all Targets on round robin manner during Discovery phase.
