TMS570LC4357: Halcogen User's Manual

HALCOGEN –> RM48L952ZWT_FREERTOS –> VIM RAM:

What do HighLevelInterrupt and LowLevelInterrupt mean? For GIO and HET, this is obviously the front and bottom of the signal. What do they mean for the exchange channels, for example, spi2HighLevelInterrupt (17) and spi2LowLevelInterrupt (30)? I did not find anything in HALCoGen-Help.

Sincerely, Talgat Burganov.

    Hello,
    Actually, High and Low level interrupts are not related to level of signal. High and Low level interrupts are mapped to different VIM channels and in that way to corresponding interrupt priority. A lower numbered channel in IRQ has higher priority.

    You can find more information on VIM and channel mapping in chapter 15 of TRM ( www.ti.com/.../RM48L952 )

    Best regards,
    MIro
