The difference between an embos interrupt and a zero latency interrupt

The difference between an embos interrupt and a zero latency interrupt are the interrupt priority level and the usage of OS _enterinterrupt ()/os_leaveinterrupt () or Os_enternestableinterrupt ()/os_leavenestableinterrupt ().

Example of an embos interrupt function:

 void  Os_com_isrhandler (void   int   Dummy;  Os_enternestableinterrupt ();       Dummy  = Us_rhr;  //  call Embos API functions here  Span style= "color: #000000;" > Os_leavenestableinterrupt ();}  void  Uart_init (void   * os_arm_isrsetprio (                         140); Set prio >    Os_arm_enableisr (Isr_id_usart);}  

Example of a Zero latency interrupt function:

void Os_com_isrhandler (void) {  int  Dummy;   = us_rhr;        // never call Embos API functions here }void uart_init (void) {  Os_arm_installisrhandler (Isr_id_usart, (OS_ISR _handler*) os_com_isrhandler);  Os_arm_isrsetprio (  );                      Set Prio <  Os_arm_enableisr (Isr_id_usart);}
