Interfaces Protocols
interfaces support STS12CFRM: middle interface (Midbus), access internal registers (AIRbus) interface.
Midbus Interface
Midbus interface simple synchronous full-duplex data path bus. STS12CFRM Midbus runs 77.76 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 Interface
AIRbus interface provides access internal registers using simple synchronous internal processor 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.
