11.6 Serial peripheral interface
11.6.1
Register description
The ADC1010S 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 pin 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 18
).
Table 17.
[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 18
).
