ADC1213S series
Single 12-bit ADC; serial JESD204A interface
11.6 Serial Peripheral Interface (SPI)
11.6.1
Register description
The ADC1213S serial interface is a synchronous serial communications port allowing for
easy interfacing with many industry microprocessors. It provides access to the registers
that control the operation of the chip in both read and write modes.
This interface is configured as a 3-wire type (SDIO as bidirectional pin).
Pin SCLK acts as the serial clock and pin CS acts as the serial chip select.
Each read/write operation is sequenced by the CS signal and enabled by a LOW level to
to drive the chip with N bytes, depending on the content of the instruction byte
(see
Table 14
).
Table 14.

R/W indicates whether a read (logic 1) or write (logic 0) transfer occurs after the instruction byte.

Bits W1 and W0 indicate the number of bytes transferred.

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 incremented to access subsequent addresses.
The steps involved in a data transfer are as follows:
1. The falling edge on pin CS in combination with a rising edge on pin 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 be 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 pin CS indicates the end of data transmission.
