I am facing a problem that while executing a serial receive interrupt my program needs to service a timer0 interrupt. The program is not jumping to the timer0 isr till the uart isr is fully complete even an overflow is generated and interrupt has been enabled ??
.... not realizing that the 'priority' associated with "interrupt number" ONLY apply if the interrupts happen in the same cycle. the ONLY way to interrupt an interrupt is to have different IP priorities.
