3.0 PROGRAMMING INFORMATION
This Section provides the specific information necessary to operate the
AVME9670A non-intelligent carrier board.
The board is addressable on 1K byte boundaries in the Short I/O (A16)
Address Space. This Acromag VME64x bus non-intelligent slave (carrier
board) has a Board Status register, but no identification information.
Identification information is provided per the Industrial I/O Pack logic
interface specification on the mezzanine (IP) boards which are installed on
the carrier. The 1K byte of memory consumed by the board is composed of
blocks of memory for the I/O and ID spaces of up to four IP modules. The
rest of the 1K byte address space is unused, or contains registers or memory
specific to the function of the carrier board. The memory map for the
AVME9670A is shown in Table 3.1A.
The Input/Output (IO) and Identification (ID) spaces of each IP are accessible
via the VME64x bus Short I/O space as shown in Tables 3.1A. The carrier
board may optionally occupy memory in the VME64x bus standard (A24)
address space, if needed for IP modules containing Memory space. IP
memory will only be mapped into the standard memory space if it is
enabled for a particular IP per the user programmable IP Memory Enable
Register (see Table 3.1B and subsequent description). The starting memory
address for each enabled IP and the memory size for each enabled IP
module is user-programmable via its associated IP Memory Base Address &
Size Register (see Table 3.1B and subsequent description).
