ADVANCE INFORMATION
The logic I/O pins of the DUT support different functions depending on the device start-up mode chosen by the GPIO1 input level upon POR.
The default logic input pin states are determined by onboard pullup or pulldown resistors, but some input pins can be driven to high or low state by the MCU output or DIP switch control. The MCU can be controlled from a PC running TICS Pro software to program the device registers through I2C or SPI and also drive the DUT logic inputs. To allow the MCU to control the pin input, SW[2] must be set to on.
See Table 3-3 for the logic pin mapping tables for the device start-up modes.
GPIO1 Input Level1 | Start-up Mode |
---|---|
0 | I2C Mode |
1 | SPI Mode |
