REPEATEROPERATION
The repeater mode of operation allows a data word that has been
received by the HI-8282 to be placed directly into its FIFO for
transmission. After a 32-bit word has been shifted into the receiver
shiftregister,the
flagwillgolow. Alogic"0"isplacedontheSEL
line and
is strobed. This is the same procedure as for normal
receiver operation and it places the lower byte (16) of the data word
on
the
data
bus.

from the receiver latches first by use of SEL input. During repeater
operation however, the lower byte of the data word must be read
first. This is necessary because, as the data is being read, it is also
being loaded into the FIFO and the transmitter FIFO is always
loadedwiththelowerbyteofthedatawordfirst.
