Functional characteristics

1. Compliance

Compliant with VMEbus specifications ANSI/IEEE STD 1014-1987, IEC 821, and 297

Supported Address Modifiers: 3D, 39/2D, 29

Supports A24/A16 addressing, data transmission supports D32/D16/D08 (EO)

2. Built in testing (BIT)

Input testing: By setting bits in the Control and Status Register (CSR), the input is placed in test mode. At this time, the data read through the input port is from the onboard test register rather than on-site data. The test register has the same address as the input data port and supports both online and offline testing

Output testing: The contents of the output data register can be read at any time to support online testing; By setting the bit in CSR, the output can be placed in offline testing mode, where the open collector output is completely disabled. This allows for testing of data writing and reading modes in the output register without affecting the output

Power on/reset state: The board is in test mode, and the output data register should be initialized before going online to avoid uncertain states

3. Addressing scheme and address mapping

Addressing organization: Organized by 8-bit ports, including 4 input ports and 4 output ports, located on a long word boundary above the board ID and CS registers, occupying 16 bytes of address space

Address Mapping:

$00: BD ID (Board ID)

$02: Control and Status Register (CSR)

$04- $07: Input data register 0-3

$08- $0B: Output data register 0-3

$0C – $0F: Reserved

Input characteristics
