Serial Interface
The AS1116 contains a 16bit SPI interface to access the internal data and control registers of the device (see Digit- and Control-Registers
on page 11) . The SPI interface is driven with the rising edge of SCL. A falling edge on LD signal indicates the beginning of an access on the
SPI interface, the rising edge on LD determines an access on SPI. An access must consist of exactly 16bits for write operation and 8bits for read
Table 6 shows the structure of the 16bit command word for writing data. The bits D0 to D7 are the data information, bits D8 to D12 are the
address bits, D13 is set to ‘0’, bit D14 is defining the read (D14 = ‘1’) or the write (D14 = ‘0’) configuration and bit D15 is a don’t care bit.
In Table 7 on page 11 the 8bit command word for the read operation can be found.
Bit D0 (write operation) or bit D8 (read operation) is the first bit to shift into the SPI interface after the falling edge of LD. Bit D15 is the last bit to
write to SPI before rising edge of LD.
At a read operation an 8bit operation is executed (see Figure 18) . At the first rising edge of SCL after the rising edge of LD D7 of addressed
register is written to SDO pin. At the next rising edge of SCL D6 is written to SDO pin. LD must be kept high during reading data from a internal
data or control register of AS1116.
