        4.2. Avalon® Memory-Mapped Interface Signals
| Signal | Direction | Description | 
|---|---|---|
| csr_mch_write | In | Assert this signal to request a write to Avalon® memory-mapped address decoder. | 
| csr_mch_read | In | Assert this signal to request a read to Avalon® memory-mapped address decoder. | 
| csr_mch_address | In | Use this bus to specify the register address you want to read from or write to. | 
| csr_mch_writedata | In | Carries the data to be written to the specified register. | 
| csr_mch_readdata | Out | Carries the data read from the specified register. | 
| csr_mch_waitrequest | Out | When asserted, this signal indicates that the IP is busy and not ready to accept any read or write requests. |
