MAX32675 IRQ vector table in max32675.h: entries for interrupts that do not exist #736

Closed oledreessen closed 9 months ago

oledreessen commented 9 months ago

in the IRQ vector table for the MAX32675 are entries for peripherals that do not exits. examples: RTC_IRQn, / 0x13 0x004C 19: RTC / TMR5_IRQn, / 0x1A 0x0068 26: Timer 5 / UART1_IRQn, / 0x1F 0x007C 31: UART 1 / SPI2_IRQn, / 0x22 0x0088 34: SPI2 /
I2C1_IRQn, / 0x34 0x00D0 52: I2C1 /

The above list is not complete.

Hi @oledreessen , some of our chips that have different part numbers share most of the die. The MAX32675 is a mix of a MAX32670 and a die that has no part number as it is not a standalone block. The IRQs that you have mentioned lie within the reserved regions mentioned in the datasheet as they are used in the MAX32670. In order to get the added functionality of the newer die, some blocks are left unconnected to free up space for the the new features. Therefore they still exist, but will not do anything. We generate our register files based on the die not the part number. So they still exist in the headers.

Thanks @oledreessen and @EricB-ADI. Will close this out for now since it doesn't affect functionality.

@sihyung-maxim FYI - perhaps this is something we can address with the register file generator in the future.
