  • Page 18: Addressing Board Configuration Registers

    2.2 Addressing Board Configuration Registers The VMEM-F1 occupies 4 kByte in the VMEbus A16 address space (Short I/O) where the board con- figuration registers are situated. The base address of this 4 kByte block is selected using a jumper (see Chapter 3 Configuration for more details).

  • Page 19: Addressing Memory

    In order to reach the whole of the 192 MByte, the area is paged in blocks of 4 MByte. On the VMEM-F1, one page represents one FLASH bank, which is physically built up of a pair of FLASH chips. Within one page, the whole memory can be linearly addressed. The FLASH page is se- lected via the FLASH page register (see...).

    Reserved Reserved MA23 MA22 Reserved Reserved This register must be set to 00 HEX, as by default the VMEM-F1 occupies 4 MByte of address space (reserved for future extensions when using different Extension Modules). Memory SIze MA23 MA22 (HEX) 4 MByte Page 2- 6 ©...

  • Page 21: Memory Address Modifier Code Register

    The full address of the host CPU has to be set accordingly. VM42 Example: the base address is set to $82xxxxxx for user defined AM code 10 HEX - 17 HEX. July 30, 1997 © PEP Modular Computers Page 2- 7...

  • Page 22: Flash

    Notes This register contains the currently used FLASH page, which represents a unique FLASH chip pair. The VMEM-F1 board that offers 64 MBytes of FLASH memory has 16 pages, starting at page 0 up to page F HEX. The VMEM-F1-PB1 (FLASH Extension Module), offering 128 MBytes of FLASH memory has 32 pages, starting with page 10 HEX up to page 2F HEX.

    Chip Select (CS), VMEM-F1-PB1 2.5 Default FLASH Enable Default FLASH Enable is jumper selectable (J5). If selected, the VMEM-F1 responds to the A24 ad- dress without being initialized. The default base address is 00 00 00 HEX in address space. The default page is 0.

  • Page 24: Ready-To-Busy Transition Interrupt

    In some cases, it may be more effective to interrupt the CPU instead of polling the end of an erase or program operation. The VMEM-F1 therefore provides a facility to generate a VME Level 2 interrupt re- quest each time the FLASH memory changes from busy to ready status. The interrupt function is con- trolled by the interrupt control register and interrupt vector register.
