9.2. Avalon® Memory-Mapped Interface Signals
Signal | Direction | Description |
---|---|---|
csr_mac_write csr_phy_write csr_mch_write csr_dphy_rcfg_write |
In | Assert this signal to request a write to Avalon® memory-mapped address decoder. |
csr_mac_read csr_phy_read csr_mch_read csr_dphy_rcfg_read |
In | Assert this signal to request a read to Avalon® memory-mapped address decoder. |
csr_mac_address csr_phy_address csr_mch_addresscsr_dphy_rcfg_address |
In | Use this bus to specify the register address you want to read from or write to. |
csr_mac_writedata csr_phy_writedata csr_mch_writedata csr_dphy_rcfg_writedata |
In | Carries the data to be written to the specified register. |
csr_mac_readdata csr_phy_readdata csr_mch_readdata csr_dphy_rcfg_readdata |
Out | Carries the data read from the specified register. |
csr_dphy_rcfg_readdatavalid |
Out | When asserted, this signal indicates that the read data is valid. |
csr_mac_waitrequest csr_phy_waitrequest csr_mch_waitrequest csr_dphy_rcfg_waitrequest |
Out | When asserted, this signal indicates that the IP is busy and not ready to accept any read or write requests. |
