#185537 - Shared interrupts. |
I am using atmel microcontroller 89LP4052. In this the UART and the SPI share the same interrupt.
1. Will I loose a SPI interrupt if the interrupt occurs during the execution of the interrupt service routine for UART. 2. Will I loose aa UART interrupt if the interrupt occurs during the execution of the interrupt service routine for SPI. 3. Can I nest the interrupts to check for SPI interrupt inside the ISR of UART and vice versa. thanks in advance. Shankara Rao |
