     NAME       : HCPAMTE
     DESCRIPTION: ASIT Management Table Entry for PTRM
                  i-ASITs
     DSECT      : AMTE
     FUNCTION   : There is one ASIT Management Entry for each PTRM
                  address space.  The ASIT Management Table resides
                  in HCPRSM and consists of 16 doubleword table
                  entries.
                  The ASIT Management Table contains entries that
                  are either marked invalid or contain the i-ASIT
                  for a PTRM address space.
     LOCATED BY : RSAASITB - ASIT table for the PRM address spaces
                  RSAASITB + (Address space index * AMTLENTH)
                  AMTNEXT  - the next contiguous AMTE
     CREATED BY :
                  All AMTEs are contained in HCPRSM.  Each entry is
                  initialized as invalid by HCPPRMIN.
     DELETED BY : none
     SERIALIZED : RSAAFLK - PTRM i-ASIT Resolution Lock
     COMMENTS   : none
