* Revision history:
* 05/16/03 brr Added PK_DH_CP_Byte_Length.
* 05/15/03 brr Added masks for command & bus errors.
* 02/20/02 brr Removed references to the queue structure.
* 07/30/01 bac Changed word size macros to take a queue control pointer.
* 05/30/01 bac Changed the macro BYTES_TO_PKDIGITS to correctly compute the
* number of digits by rounding up.
* 05/22/01 dws Reversed the order of data_addr_ms and data_addr_ls in
* PK_LDST_CMD_BLOCK_t.
* 04/16/01 jke moved status and return types to n8_enqueue_common.h
* and genericized for use in EA and PK
* 04/05/01 bac Added BYTES_TO_PKDIGITS and PKDIGITS_TO_BYTES
* 03/30/01 dws Removed the typdef for PK_BIGNUM_DIGIT.
* 03/29/01 dws Removed simulator-specific declarations.
* Changed uint32 to uint32_t.
* 03/28/01 jke copied from n8_pk.h
