T48C862-R4 [Preliminary]
Deactivating the SSI (SIR = 1) in mid-telegram will immediately stop the shift clock and
latch the present contents of the shift register into the receive buffer. This can be used
for clocking in a data telegram of less than 8 bits in length. Care should be taken to read
out the final complete 8-bit data telegram of a multiple word message before deactivat-
ing the SSI (SIR = 1) and terminating the reception. After termination, the shift register
contents will overwrite the receive buffer.
