11.5 Serial Peripheral Interface (SPI)
11.5.1
Register description
The ADC1443D serial interface is a synchronous serial communications port, which
allows easy interfacing with many commonly used microprocessors. It provides access to
the registers controlling the operation of the chip.
The register bits are either global or local functions:
A global function operates over the full IC behavior. A local function operates on one
or several previously selected channels only. If a channel is selected, the next WRITE
command in the local registers applies to the selected channel. The WRITE command
has no impact on channels that are not selected. This makes it possible to apply
different configurations on each channel by first selecting a specific channel and then
all the related settings.
Select only one channel during a READ operation of the local registers. If several
channels are selected, the READ operation occurs on the channel A.
Programming all registers at the same time is required:
The IC allows the storage of a set of settings for the addresses 06h to 23h, which
enables the configuration of all registers simultaneously by setting bit TRANSFER to
HIGH (see
Table 32
). This bit is autoclearing. This function can be disabled using SPI
(bit TRANS_DIS in
Table 32
). The registers are then updated at each WRITE
operation.
The transfer function does not apply to a READ operation.
The SPI interface is configured as a 3-wire type: pin SDIO is the bidirectional pin, pin
SCLK is the serial clock input and SCS_N is the chip select pin.
A LOW level on pin SCS_N initiates each READ/WRITE operation. A minimum of 3 bytes
is transmitted (two instruction bytes and at least 1 DATA byte; see
Table 18
).
Table 17.
Bit:
Description
Bit R/W indicates whether it is a READ (when HIGH) or a WRITE (when LOW)
operation.
Bits W1 and W0 indicate the number of bytes to be transferred after both instruction
bytes (see
Table 18
).
