Starts the flow of data processing through the specified MSPP endpoint.

DWORD mspEnableEndpoint (MSPHD ephd)

ephd MSPP endpoint handle.

• SUCCESS
• CTAERR_BAD_ARGUMENT
  The function argument had an invalid value or a required pointer argument was NULL.
• CTAERR_INVALID_CTAHD
  The CTA context handle is invalid.
• CTAERR_INVALID_HANDLE
  An invalid handle was passed as an argument to this function.
• MSPERR_INVALID_HANDLE

• MSPERR_ENDPOINT_BUSY
  The MSPP command arrived while servicing a previous command.
• MSPERR_DRIVER_COMMAND_FAILED
  An SPI command has failed.
• MSPERR_ENDPOINT_NOT_ALLOCATED
  The MSPP endpoint is defined, but not yet allocated on the board.

• MSPEVN_ENABLE_ENDPOINT_DONE
  Generated when the data flow between MSPP endpoints is halted following a call to mspEnableEndpoint. The event.value field can contain the following:
• SUCCESS
• MSPRSN_FAILED_TO_START
  The MSPP service is unable to start the on-board
  resource.

Created MSPP endpoints are enabled, by default. When invoking mspEnableEndpoint, specify the endpoint handle (ephd) of the connected endpoint.

The mspEnableEndpoint function can also be used to re-establish the data flow through a channel that had previously been disabled.
