Preliminary Technical Data
AD9736/AD9735/AD9734
configurations or initiating a software reset is highly
recommended. In the event of unexpected programming sequences
the AD9736 SPI may become inaccessible. For example, if user
code inadvertently changes the LONG_INS bit or LSBFIRST bit the
following bits may have unexpected results. The SPI can be
returned to a known state by writing an incomplete byte (1-7 bits)
of all zeroes followed by three bytes of 0x00. This will return to
MSB first short instructions (REG00 = 0x00) so the device may be
reinitialized.

Figure 22. Timing Diagram for SPI Register Read
After the last instruction bit is written to the SDIO pin the driving
signal must be set to a high impedance in time for the bus to turn
around. The serial output data from the AD9736 will be enabled by
the falling edge of SCLK. This causes the first output data bit to be
shorter than the remaining data bits as shown in Figure 22.
PIN MODE OPERATION
When the PIN_MODE input (pin L1) is set high, the SPI port is
disabled. The SPI port pins are remapped as shown in Table 10. The
function of these pins is described in Table 11. The remaining
PIN_MODE register settings are shown in Table 5, the SPI register
map.

Table 11. PIN_MODE Input Functions
Care must be taken when using PIN_MODE since only the control
bits shown in Table 11 can be changed. If the remaining register
default values are not suitable for the desired operation
PIN_MODE cannot be used.
