- Synchronous reset
This constant influences the implementation of the reset signal that is routed to
all resetable flipflops.
TRUE - A synchronous reset is implemented (default value).
FALSE - An asynchronous reset is implemented.
*DWHG&ORFN
- Power save function
This constant influences the implementation of the system clock signal.
TRUE - The adapter detects when it is in a complete idle state and turns the
clock signal off, i. e. there is no traffic on the MultiMediaCard bus, the command
and data controller are in the idle state and no system command needs to be
serviced. The adapter is awakened with the next request on the application
interface.
FALSE - The system clock is passed directly to all modules of the adapter
(default value).

- Power management implementation enable
This constant controls the implementation of the ROSA power management
command support.
TRUE - Power management commands (CAM_16 - CAM_19) are supported.
FALSE - Power management is not implemented.
