#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.
