11.6 Serial Peripheral Interface (SPI)
11.6.1
Register description
The ADC1115S125 serial interface is a synchronous serial communications port that
allows easy interfacing with many commonly-used microprocessors. It provides access to
the registers that control the operation of the chip.
This interface is configured as a 3-wire type (SDIO as bidirectional pin)
Pin SCLK is the serial clock input and CS is the chip select pin.
Each read/write operation is initiated by a LOW level on CS. A minimum of three bytes is
transmitted (two instruction bytes and at least one data byte). The number of data bytes is
determined by the value of bits W1 and W2 (see
Table 17
).
Table 16.
[1]
Bit R/W indicates whether it is a read (logic 1) or a write (logic 0) operation.
[2]
Bits W1 and W0 indicate the number of bytes to be transferred after the instruction byte (see
Table 17
).
