Interfaces &
Protocols
Two interfaces support the STS12CFRM: the middle interface (Midbus),
and the access to internal registers (AIRbus) interface.
Midbus Interface
The Midbus interface is a simple synchronous full-duplex data path bus.
The STS12CFRM Midbus runs at 77.76 MHz over a single byte lane in each
direction. In the receive (RX) direction, data is transferred from the
Midbus master (RXPOH_0) to the slave. In the transmit (TX) direction,
data is transferred from the slave to the master (TXPOH_0). In each
direction, RX and TX, the Midbus can carry eight bits per clock cycle. It
includes Midbus receive data (
mrxdat_0[7:0])
and Midbus receive
enable
(mrxena_0)
lines to indicate valid data transfers in the RX
direction, and Midbus transmit data (
mtxdat_0[7:0])
and Midbus data
enable
(mtxena_0)
lines to indicate valid data requests in the TX
direction.
AIRbus Interface
The AIRbus interface provides access to internal registers using a simple
synchronous internal processor bus protocol. This consists of separate
read data (
rdata[31:0]
) and write data (
wdata[31:0]
) buses, a data
transfer acknowledge (
dtack
) signal, and a block select (
sel
). An address
(
addr[11:2]
) bus and read (
read
) signal indicate the location and type
of access within the block. The
rdata
buses and
dtack
signals can be
merged from multiple blocks using a simple OR function. The
dtack
signal is sustained until the block
sel
is removed (four-way
handshaking), meaning the AIRbus can cross clock domain boundaries. In
this block the AIRbus has a data width of 32 bits.
