WebMar 4, 2024 · The External Interrupt (EXTINT) module provides a method of asynchronously detecting rising edge, falling edge, or specific level detection on individual I/O pins of a device. This detection can then be used to trigger a software interrupt or event, or polled for later use if required. WebSelect-able clock source (internal or external) Edge select for external clock; Interrupt on overflow; Timer-0 of pic18f4550 can be used in 8-bit and 16-bit mode. Timer-0 is controlled with T0CON register. T0CON contains the individuals bits that are used to set timer in different modes and other working configurations.

WebAs I understood, the CPLD interrupts STM32 by a falling edge. In EXTI configuration and if the CPLD forces always the STM32 GPIO during the interrupt, you'll never get out from ISR since the EXTI is an edge-senstive-interrupt and not a level-sensitive-interrupt.
