2.6. Slave

The V2718 can be operated as slave for debugging purposes. It responds to VME cycles
(which must be initiated by another master, i.e. a V2718 cannot address itself as a slave)
for accessing the Dataway Display internal registers and a Test RAM (32 x 16). The
V2718 is accessed both with A32 and A24 base address (see § 3.5.1); the module is
provided with only two rotary switches for board addressing, so the addressing mode is
selected via the dip switch 3 (A24
3.5.1.
The Address map for V2718 is listed in Table 2.1. All register addresses are referred to
the Base Address of the board, i.e. the addresses reported in the Tables are the offsets
to be added to the board Base Address.
