mm_write 1 Input

Write access to the register ports.

mm_addr 16 Input

Address to access the register ports.

mm_rdata 32 Output

When mm_rdata_valid is high, mm_rdata holds valid read data.

mm_rdata_valid 1 Output

Valid signal for mm_rdata.

mm_wdata 32 Input

When mm_write is high, mm_wdata holds valid write data.

mm_waitrequest 1 Output Busy signal for mm_readdata.
