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. T0Con is an 8-bit register.
