[ssean]

Hello.

LPCMP module has 2 power mode - high power and low power mode. (CMP_HPMD register)

What is difference?

What is benefit when use low power mode?

FYI, I used LPCMP module for WKPU only.

So I wondering which mode is better in standby.

Thank you.

Hello @ssean,

This is specified in the DS, Section 10.3 Low Power Comparator (LPCMP).

The high speed mode has a much shorter propagation delay, but the current is 14x higher.
