Description
The RST_N input is asynchronous and active LOW, and clears the TDA8296. When
RST_N goes LOW, the circuit immediately enters its Reset mode and normal
operation will resume four XIN signal falling edges later after RST_N returns HIGH.
Internal register contents are all initialized to their default values. The minimum width
of RST_N at LOW level is four XIN clock periods.
Crystal oscillator input pin. In Slave mode (typically), the XIN input simply receives a
16 MHz clock signal (f
Oscillator mode, a fundamental 16 MHz (typically) crystal is connected between
pin XIN and pin XOUT.
Crystal oscillator output pin. In Slave mode, the XOUT output is not connected. In
Oscillator mode a fundamental 16 MHz (typically) crystal is connected between pin
XIN and pin XOUT.
