Using the STM32L452. According to PM0214 Rev 10 page 40 there are 256 exceptions utilizing memory 0x0000 to 0x0400. According to RM0394 Rev 4 page 324 Table 46 only identifies 84 interrupts utilizing memory up to 0x0190. In order to be safe shouldn't...

Thanks for responding. In free running it only reads 0. When it hits the breakpoint after the read, the LPTIM is enabled and there is a value in the CNT register even though it read a zero (0). (see attached document) Can manually press the RD (read)...
