
Name: DMAC Component Parameters Register 2

Size: 64 bits

Address offset: 0x3e8

Read/write access: read
This is a constant read-only register that contains encoded information about the component parameter settings. The reset value depends on
coreConsultant parameter(s).
Note: If DMAH_RETURN_ERR_RESP is set to True, the DMAC returns an ERROR response to an illegal register access, which includes accessing
registers that have been removed during DMAC configuration. If DMAH_RETURN_ERR_RESP is set to False, DMAC always returns an OK
response.
Bits 63:32 include the Multi-Block type parameter for Channel 0 to Channel 7. Bits 31:0 include the configuration parameters for Channel 0.
