/*****************************************************************************
* PURPOSE: This function configures the PLC–5/40V to continuously copy.
* This function is private to this file and is common to all
* the continuous copy functions: Initiate continous copy to VME,
* Initiate continuous copy from VME, Halt continuous copy to
* VME and Halt continuous copy from VME.
*
* INPUT: PLC540V_CONT_COPY_COMMAND ccCmd contains the continuous copy
* command which should be issued to the PLC–5/40V: continuous
* copy to VME or continuous copy from VME.
*
* PLC540V_CONT_COPY_MODE ccMode contains the mode of the
* continous copy command which is being sent to the PLC–5/40V:
* enable or disable continous copy.
*
* ULONG vmeDataAddr contains the VME address where the
* processor file memory will be written into.
*
* UWORD vmeDataSize contains the number of 16 bit words which
* will be written.
*
* ULONG vmeCmdBlkAddr contains the VME address where the
* command block will be copied to so the PLC–5/40V can
* access its information.
*
* UWORD baseAddress contains the base address of the
* PLC–5/40V.
*
* VME_DATA_WIDTH_TYPE width contains the data width that
* should be used for the copy operations. It can be D16
* or D08.
*
* VME_ADDRESS_MODIFIER_TYPE addrMod defines the address space
* in which the VME data is accessed. It can be A16 or A24.
