Read/write access: read
This is a constant read-only register that contains encoded information about the component parameter settings for Channel 7. 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.

Reserved
Puts the AHB slave interface into test mode. In this mode, the read back
value of the writable registers always matches the value written. This
bit does not allow writing to read-only registers.
0 = Normal mode
1 = Test mode
