The TFP410 device configuration can be programmed by several different methods to allow maximum flexibility for the user’s application. Device configuration is controlled depending on the state of the ISEL/ RST pin, configuration pins (BSEL, DSEL, EDGE, VREF) and state pins ( PD, DKEN). I2C bus select and I2C RESET (active low) are shared functions on the ISEL/ RST pin, which operates asynchronously.
Holding ISEL/ RST low causes the device configuration to be set by the configuration pins (BSEL, DSEL, EDGE, and VREF) and state pins ( PD, DKEN). The I2C bus is disabled.
Holding ISEL/ RST high causes the chip configuration to be set based on the configuration bits (BSEL, DSEL, EDGE) and state bits ( PD, DKEN) in the I2C registers. The I2C bus is enabled.
Momentarily bringing ISEL/ RST low and then back high while the device is operating in normal or power-down mode will RESET the I2C registers to their default values. The device configuration will be changed to the default power-up state with I2C enabled. After power up, the device must be reset. It is suggested that this pin be tied to the system reset signal, which is low during power up and is then asserted high after all the power supplies are fully functional.
