(010) Idler
The Idler Block corresponding to state 010 continuously is the default module running an "idle process". It awaits an interrupt corresponding to "Receive FIFO non-empty", unpon which it transitions to state 011 - Read.
Programming Details
Ports
- Clk: [in] clock
- Rst: [in] asynchronous reset
- Eth_iINT: [in] EC interrupt pin
- state_in: [in] 3-bit FPGA state value
Transceiver Control Lines
- TxRx_Din: [in] EC control register return value
- TxRx_Done: [in] "Done" signal from Transceiver.
- TxRx_Go: [out] "Go" signal to read an EC control register byte
- TxRX_RiW: [out] active-high read, active-low write flag
- TxRx_Aout: [out] _VECTOR (7 downto 0);
