Possible incosistence into MPC5777C Reference Manual (Chapter 39 - IGF / Falling threshold register)

Trying Input Glitch Filter (IGF), of MPC577C, it looks like each the IGF's channels has its own IGF_FTHR register;

whereas MPC5777C Reference Manual (Document Number: MPC5777CRM / Rev. 8.1, 09/2018 - Chapter 39

Input Glitch Filter (IGF)), defines only one IGF_FTHR register per each IGF module (IGF_0 or IGF_1), see yellow marked text into  below extracts from reference manual.


I didn't find any related "errata", so I ask if really all IGF channels have proper IGF_FTHR (should be IGF_FTHRn)  register located at the address 0h base + 20h offset + (64d x i), where i=0d to 45d ?

And consequently the Reference Manual should be corrected?


Thank you,

Enrico Ferrari
