STLUX385A :There are some problems when I configured a coupled SMED

Hi,

According to the ''appliction note AN4461'',I configure  SMED4 and SMED5 in synchronous coupled SMEDs mode to generate a PWM output (PFC MOSFET driving signal)

In RM0380 reference manual, page 191 ,it says

0690X00000608GHQAY.png

And in page 192

To make PWM5  generate a coupled signal,I configured  SMED5 drive out bit is ON by SMED configurator 1.0

I have some problems When I configured  SMED4 and SMED5 to realize the state transition.

Is that mean If I configured the ''Hold jump waking up when the corresponding coupledSMED will go in HOLD'' is ON

 ,when the coupled SMED (SMED5) is on the hold state ,the SMED4 will jump into the hold state.

If it is true ,that will be contradictory  with the content i

n RM0380 reference manual, page 191.
