|
* Revision history:
|
|
* 05/15/03 brr Added definition for DEF_RNH_BIGERROR_IRQ_BITS.
|
|
* 11/25/02 brr Removed definition of RNG_ALL_UNITS.
|
|
* 03/27/02 hml Removed obsolete include file
|
|
* 03/01/02 brr Moved RNG_ALL_UNITS to this file since its used by SAPI.
|
|
* 10/23/01 dkm Moved seed defines to n8_pub_rng.h.
|
|
* 10/12/01 dkm Moved public portion to n8_pub_rng.h.
|
|
* 09/17/01 bac Removed buffer_lenLog2 from N8_RNG_Parameter_t.
|
|
* 09/17/01 bac Removed buffer_source from N8_RNG_Parameter_t.
|
|
* 09/14/01 msz Fixed circular dependency.
|
|
* 09/14/01 bac Changed seed source values from enums to #defines so that they
|
|
* cannot inadvertantly change again. Removed N8_RNG_BufferSrc_t
|
|
* as it is no longer needed.
|
|
* 09/07/01 msz Changes to support host seed, and cleanup work
|
|
* 09/06/01 bac Renumbered enums to start with non-zero (BUG #190).
|
|
* 07/19/01 bac Moved RN_Request_t to n8_enqueue_common.h.
|
|
* 06/28/01 bac Added userBuffer_p and numBytesRequested to RN_Request_t in
|
|
* order to facilitate the callback function.
|
|
* 06/21/01 msz Added RN_QUEUE_INIT_OPEN_FAILED
|
|
* 06/19/01 hml Added requestStatus, numElementsProvided, unit and chip to
|
|
* the RN_Request_t. Moved protos to RN_queue.h.
|
|
* 05/07/01 bac Added RNG_Status_Seed_Shift.
|
|
* 04/24/01 dws Fixed bracket style for RNG_Sample_t.
|
|
* 04/11/01 bac Standardization by changing type names to include _t.
|
|
* 04/09/01 jke Original version.
