Stellar E vs Stellar P for inverter

ay

Hello, I am interested in the Stellar E and P series for the purpose of motor control, with an inverter topology that has 12 independent switches and requires fine control of the offset between some of the waveforms.

1) The E series is marketed as optimized for traction inverters. Is there anything it can do in power converter applications that the P series cannot do? Does E series do something better or more easily, or just cheaper?

2) Is there any difference between the HR timer peripherals of the E and P series, except that E has 2 x 6 channels and P has 2 x 8?

3) How does the GTM4 of the P series compare to the advanced control timer of the E series? I can't find information about GTM4 on the product pages.

4) Is it correct that the E series does not have any interface for external RAM, not even quad SPI?

5) In the datasheet for E series, page 38, https://www.st.com/resource/en/datasheet/sr5e1e3.pdf, what is the meaning of the specification f_IN = 0.01 kHz minimum? Can it not convert the modulator output from an ADC such as AMC0336 if the analog input signal is DC?

Apologies, should I make a new thread for my questions about SR5?

Will the restrictions on SR6 information be lifted at some point in the future?
