ADC1213D series
Dual 12-bit ADC; serial JESD204A interface
11.6 Serial Peripheral Interface (SPI)
11.6.1 Register description
The ADC1213D 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).
SCLK acts as the serial clock, and 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 2 bytes to 5 bytes, depending on the content of the instruction byte
(see Table 14).
[1]
R/W indicates whether a read (logic 1) or write (logic 0) transfer occurs after the instruction byte
[1]
Bits W1 and W0 indicate the number of bytes transferred after the instruction byte.
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.
