TDA523x
Functional Description
A second source that can trigger a reset is a brown out event. Whenever the integrated
brown out detector measures a voltage drop below the brown-out threshold on the digital
supply, the integrity of the stored data and configuration can no longer be guaranteed;
thus, a reset is generated. While the supply voltage stays between the brown out and the
functional threshold of the chip, the NINT/NSTR pin is forced to low. When the supply
voltage drops below the functional threshold, the levels of all digital output pins (e.g.
NINT/NSTR) are undefined.
When the supply voltage rises above the brown out threshold, the IC generates a high
pulse at NINT/NSTR and remains in the reset state for the duration of t
. When the
Reset
IC leaves the reset state, the Interrupt Status register (IS) is set to FF
and the
hex
NINT/NSTR pin is forced to low. Now, the IC starts operation in the Sleep Mode, ready
to receive commands via the SPI interface. The NINT/NSTR pin will go high, when the
Interrupt Status register is read the first time.
