Change History (most recent first):
<SM10> 11/10/93 fau Update from SuperMunggio <SMG2>.
<SMG2> 9/29/93 chp Removed typedefs for unsigned types.
<SM9> 4/29/93 chp SuperMario = Ludwig B6
<LW5> 4/13/93 chp Remove unused fields from PSC_INT_TBL in conjunction with
changes to PSCEqu.a.
<LW4> 3/16/93 chp Remove the definition of the PSCIntTbl lomem which has been
superseded by an equivalent field in ExpandMem.
<LW3> 2/24/93 chp The TimeStamp structure was correct in <SM6> but the hardware
was backwards. Fix the structure one last time to reflect the
format of the UTSC in the final version of the PSC.
<LW2> 12/29/92 chp The TimeStamp structure was not reversed; the code using it was
reversed. The structure has been restored as it was in <SM5>.

<SM6> 12/8/92 chp The TimeStamp structure was reversed, causing externally clocked
devices to hang the system.
<SM5> 12/4/92 chp PSC primitive functions moved here from SerialHALPSC.c. Channel
direction constants removed.
<SM4> 10/8/92 chp Added structs and constants for accessing the Universal Time
Stamp Counter (UTSC).
<SM3> 8/13/92 chp Support for PSC rev 1 (and all references to such support)
permanently removed.
<SM2> 7/1/92 chp Updated change history for SuperMario.

<5> 6/24/92 chp Eliminate compile-time conditionals for different PSC versions.
Update PSC equates for consistency with changes in assembly
definitions elsewhere.
<4> 6/20/92 chp Changed enum syntax slightly to satisfy the overly-retentive
compiler from another famous Cupertino development tool
provider. (It thinks an enumeration list can<EFBFBD>t end with a
comma.)
<3> 6/11/92 chp Add a few more PSC constants, including one to support prototype
versions of the PSC. Use conditionals to permit building PSCHAL
for various versions of the PSC.
<2> 5/29/92 chp Reimplemented fragments of the Universal info data structures to
support base address retrieval using C idioms. Renamed a
poorly-named data type. Completed implementation of PSC register
offsets and named bits in control and status registers. Added
support for multiple inclusion.
