Interfaces Protocols
interfaces support STS1FRM: Middle interface (Midbus), Access Internal Registers (AIRbus) interface.
Midbus
Midbus interface simple synchronous full-duplex data path bus. STS1FRM Midbus runs 6.48 over single byte lane each direction. receive (RX) direction, data transferred from Midbus master (RXPOH_0) slave. transmit (TX) direction, data transferred from slave master (TXPOH_0). each direction, Midbus carry eight bits clock cycle. includes midbus receive data (mrxdat_0[7:0]) midbus receive enable(mrxena_0) lines indicate valid data transfers direction, midbus transmit data (mtxdat_0[7:0]) midbus data enable(mtxena_0) lines indicate valid data requests direction.
AIRbus
AIRbus interface provides access internal registers using simple synchronous internal protocol. This consists separate read data (rdata[31:0]) write data (wdata[31:0]) buses, data transfer acknowledge (dtack) signal, block select (sel). address (addr[11:2]) read (read) signal indicate location type access within block. rdata buses dtack signals merged from multiple blocks using simple function. dtack signal sustained until block removed (four-way handshaking), meaning AIRbus cross clock domain boundaries. this block AIRbus data width bits.
