9.3 Feature Description

9.3.1 RESET Operation

The DIX4192-Q1 includes an asynchronous active low reset input, RST (pin 24), which may be used to initialize

the internal logic at any time. The reset sequence forces all registers and buffers to their default settings. The

reset low pulse duration must be a minimum of 500 ns in length. The user must not attempt a write or read

operation using either the SPI or I2C port for at least 500 μs after the rising edge of RST. See Figure 6 for the

reset timing sequence of the DIX4192-Q1.

In addition to reset input, the RESET bit in control register 0x01 may be used to force an internal reset, whereby

all registers and buffers are forced to their default settings. Refer to Control Registers for details regarding the

RESET bit function.

Upon reset initialization, all functional blocks of the DIX4192-Q1 default to the power-down state, with the

exception of the SPI or I2C host interface and the corresponding control registers. The user may then program

the DIX4192-Q1 to the desired configuration, and release the desired function blocks from the power-down state

using the corresponding bits in control register 0x01.
