I have a basic questions about the IRQ-pin function of KEA128. So, please help me.


Q1 : Glitch filter setting for the IRQ-pin
According to the KEA128 reference manual rev2, there are the following setting bits.
   PORT_IOFLT0[FLTRST]  :  for RESET-pin and IRQ-pin ( Section also explain this. )
   PORT_IOFLT1[FLTIRQ]   :  for only IRQ-pin

Are these correct? Or, is the FLTRST-bit a mistake of only for a RESET-pin?


Q2 : KEA128 has both PORT_IOFLT0 and PORT_IOFLT1. But KEA64 has only one register of PORT_IOFLT.

Can't user use glitch filters for peripheral such as PWT or FTM if user is using KEA64?


Thank you very much in advance.
