    Hi,

    I am using LPC2368. It has pretty complex code running with 1 Timer interrupt (100uS continuous) , 2 UART interrupts, 1 SPI Interrupt, 1 USB interrupt and main loop.

    Watchdog timer is of 5 sec and is feed in main loop and in different places.

    Why should we call secure function in handler mode? What is the design purpose for this?  As we know, none-secure side can also call secure function in thread mode.
