An address/command byte, shown in Table 9, pre-
cedes a data register. The first bit of the
address/command byte determines whether a read
or a write is requested. The next six bits contain
the address. The line interface responds to address
16 (0010000). The last bit is ignored.
The data register, shown in Table 10, can be writ-
ten to the serial port. Data is input on the eight
clock cycles immediately following the ad-
dress/command byte. Bits 0 and 1 are used to
clear an interrupt issued from the INT pin, which
occurs in response to a loss of signal or a problem
with the output driver.

Writing a "1" to either "Clear LOS" or "Clear
DPM" over the serial interface has three effects:
Writing a "0" to either "Clear LOS" or "Clear
DPM" enables the corresponding interrupt for
LOS or DPM.
Output data from the serial interface is presented
as shown in Tables 11 and 12. Bits 2, 3 and 4 can
be read to verify line length selection. Bits 5, 6
and 7 must be decoded. Codes 101, 110 and 111
(Bits 5, 6 and 7) indicate intermittent loss of sig-
nal and/or driver problems.
SDO goes to a high impedance state when not in
use. SDO and SDI may be tied together in appli-
cations where the host processor has a
bi-directional I/O port.
