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
Hi Petr,
many thanks for your clarifications/confirmations.

Hi Enrico,
yes, this is inconsistency in the RM. The Falling edge threshold register exist for each channel just like Rising edge threshold register.
Falling edge threshold register address can be calculated as "Address: 0h base + 20h offset + (64d × i), where i=0d to 45d"
The RM needs to be updated to include a Ffalling threshold register for each channel. There has already been a docs ticket submitted about this.
BR, Petr
