void interrupt ISR_SERRQ (void)
- The interrupt service routine. This one checks the interrupt flag register of each port, clears
the interrupt and sets the global interrupt flag. In this simple program, where only port is
receiving at a time (and where the default settings provide a different interrupt for each port) it
is sufficient only to know that an interrupt has occurred. In situations where it is unclear which
port generated the interrupt, this IRS will need to be modified.
Page 5-46 of the UART data sheet shows how to use the Interrupt Enable Register to set the
conditions for interrupt : for example, setting the board to generate an interrupt whenever a
character has been received, or when the receive FIFO has filled to a certain level, or a
character has been successfully transmitted.
Void far *Install (void interrupt (*faddr) ( ), int vect_num )
- Installs the given ISR onto the given interrupt vector
void DeInstall (void interrupt (*oldISR) ( ), int vect_num)
- Re-installs the old ISR.
