RM4x N2HET : Maximum hr clock achievable

Hello there,

I am using the RM4x HDK Hercules microcontroller. 

I set my VCLK2 to 200 MHz, but I observe using Halcogen that the hr prescale value cannot be change to 0 to get a HR clock of 200 MHz. Could you please tell me what is the maximum HR frequency achievable with N2HET ? 

thank you 

Best regards
