stm32/stm32_it: Enable PVD_PVM_IRQHandler for WB and WL MCUs.

pi-anl · dpgeorge · commit 185116ea4139 · 2024-08-20T16:39:37.000+10:00
There is a gap in support for the PVD interrupt on STM32WBxx and STM32WLxx. This has been tested on NUCLEO_WB55 with the example code: from pyb import Pin, ExtInt def callback(line): print(line) PVD = 16 exti = ExtInt(PVD, ExtInt.IRQ_RISING_FALLING, Pin.PULL_DOWN, callback) exti.swint() Before this commit the CPU locks up as soon as the final line is run. After this commit it prints "16". Fixes issue micropython#15548. Signed-off-by: Andrew Leech <andrew.leech@planetinnovation.com.au>
