HI TI experts,

Can you provide more inputs on the RTC Clock Signal as below

1. Use cases

2. Connection when not used

3. Using crystal or Oscillator

HI Board designers,

1. Use cases

A 32.768 KHz crystal or oscillator is recommended when the processor is configured for

RTC only mode

RTC + IO + DDR self-refresh mode

2. Connection when not used

32.768 KHz crystal or oscillator is optional when low power modes are not used.

Refer LFOSC0 Not Used section of the data sheet to connect the clock input when not used

3. Using crystal or Oscillator

Refer LFOSC0 Internal Oscillator Clock Source when crystal is used

Refer LFOSC0 LVCMOS Digital Clock Source section when using oscillator
