Table 13 shows four different programmable trigger levels for each configuration. The FIFO trigger level, which can
be selected, is dependent on the number of input channels. Both, a differential or a single-ended input is considered
as one channel. The processor therefore always reads the data from the FIFO in the same order and is able to
distinguish between the channels.

TIMING AND SIGNAL DESCRIPTION OF THE THS10064
The reading from the THS10064 and writing to the THS10064 is performed by using the chip select inputs (CS0,
CS1), the write input WR and the read input RD. The write input is configurable to a combined read/write input (R/W).
This is desired in cases where the connected processor consists of a combined read/write output signal (R/W). The
two chip select inputs can be used to interface easily to a processor.
Reading from the THS10064 takes place by an internal RDint signal, which is generated from the logical combination
of the external signals CS0, CS1 and RD (see Figure 37). This signal is then used to strobe the words out of the FIFO
and to enable the output buffers. The last external signal (either CS0, CS1 or RD) to become valid makes RDint active
while the write input (WR) is inactive. The first of those external signals going to its inactive state then deactivates
RDint again.
Writing to the THS10064 takes place by an internal WRint signal, which is generated from the logical combination
of the external signals CS0, CS1 and WR. This signal is then used to strobe the control words into the control registers
0 and 1. The last external signal (either CS0, CS1 or WR) to become valid makes WRint active while the read input
(RD) is inactive. The first of those external signals going to its inactive state then deactivates WRint again.
