11. Application information
11.1 Device control
The ADC1415S can be controlled via the Serial Peripheral Interface (SPI control mode) or
directly via the I/O pins (Pin control mode).
11.1.1
SPI and Pin control modes
The device enters Pin control mode at power-up, and remains in this mode as long as pin
CS is held HIGH. In Pin control mode, the SPI pins SDIO, CS and SCLK are used as
static control pins.
SPI control mode is enabled by forcing pin CS LOW. Once SPI control mode has been
enabled, the device remains in this mode. The transition from Pin control mode to SPI
control mode is illustrated in
Figure 13
.
When the device enters SPI control mode, the output data standard and data format are
determined by the level on pin SDIO as soon as a transition is triggered by a falling edge
on CS.
