XRT83SL314
REV. 1.0.1
The XRT83SL314 has the capability of providing the necessary chip selects for multiple 14-channel LIU
devices.
simultaneously for permitting access to internal registers.
determined by a chip select decoder controlled by the 3 MSBs of the address bus ADDR[10:8]. Only one LIU
(Master) requires the ADDR[10:8]. The other 5 LIU devices use the 8 LSBs for the direct address bus
ADDR[7:0]. Figure 23 is a simplified block diagram of connecting six 14-channel LIU devices for 84-channel
applications. Selection of the chip select outputs using ADDR[10:8] is shown in Table 7.
