Bits A12 to A0 indicate the address of the register being accessed. In the case of a
multiple byte transfer, this address is the first register to be accessed. An address counter
is increased to access subsequent addresses.
The steps involved in a data transfer are as follows:
1. A falling edge on CS in combination with a rising edge on SCLK determine the start of
communications.
2. The first phase is the transfer of the 2-byte instruction.
3. The second phase is the transfer of the data which can vary in length but is always a
multiple of 8 bits. The MSB is always sent first (for instruction and data bytes).
4. A rising edge on CS indicates the end of data transmission.
11.6.2
Default modes at start-up
During circuit initialization, it does not matter which output data standard has been
selected. At power-up, the device enters Pin control mode.
A falling edge on CS triggers a transition to SPI control mode. When the ADC1115S125
enters SPI control mode, the output data standard (CMOS/LVDS DDR) is determined by
the level on pin SDIO (see
Figure 29
). Once in SPI control mode, the output data standard
can be changed via bit LVDS/CMOS in
Table 23
.
When the ADC1115S125 enters SPI control mode, the output data format (two’s
complement or offset binary) is determined by the level on pin SCLK (gray code can only
be selected via the SPI). Once in SPI control mode, the output data format can be
changed via bit DATA_FORMAT[1:0] in
Table 23
.
