In up-down mode, compare value limit is 3 periods or 6 periods

[naga]

Hi ,

I am using HRTIM of STM32G4 (up-down mode, Complementary PWM).
I am confused by what the reference manulal says.

In RM0440 Rev 7 p.874,  the compare values is limited to within 3 periods of the fHRTIM clock below the period value.
However, the compare value is limited to within 6 periods in the example.
・Prescaling ratio is 32 at CKPSC=0
・0xC0/32 = 6

Which limit is correct, 3 or 6 periods?
