15.6.19 RecallHandlers

During the normal procedure for closing a handler, the DSP sends a
HSC_CloseHandler control word to the host.
In some cases, the host-side software needs to unload the handler, and
to break the connection between the DSP and the handler.
Calling RecallHandlers() will signal any running handlers to terminate. It
will also put the host into a state where it will absorb all the control
words received from the DSP without doing anything with them. The
DSP will no longer be able to communicate with any handlers. This
state will last until the DSP is reset, in which case the default handler
will be reselected.

17 Read and write carrier board registers

The SMT6035 gives you access to the carrier board registers. Thus, you can
perform any low level accesses that you might require.
Please refer to the carrier board User Manual for a description of the carrier
board registers and BAR address mapping.
The register access is specified by a BAR address and offset values.
