INTERRUPTS
S3C70F2/C70F4/P70F4
7-2
Vectored Interrupts (Continued)
EMB and ERB flags for RAM memory bank and registers are stored in the vector address area of the ROM
during interrupt service routines. The flags are stored at the beginning of the program with the VENT instruction.
Enable flag values are saved during the main routine, as well as during service routines. Any changes you make
to enable flag values during a service routine are not stored in the vector address.
When an interrupt occurs, the EMB and ERB values before the interrupt is initiated are saved along with the pro-
gram status word (PSW), and the EMB and ERB values for the interrupt are fetched from the respective vector
address.
Then, if required, you can modify the enable flags during the interrupt service routine. When the interrupt service
routine is returned to the main routine by the IRET instruction, however, the original values saved in the stack
are restored and the main program continues program execution with these values.
Software-Generated Interrupts
To generate an interrupt request from software, the program manipulates the appropriate IRQx flag. When the
interrupt request value in the IRQx flag is set, it is retained until all other conditions for the interrupt have been
met, and the service routine can be initiated.
Multiple Interrupts
By manipulating the two interrupt status flags (IS0 and IS1), you can control service routine initialization and
thereby process multiple interrupts simultaneously.
Power-Down Mode Release
An interrupt (with the exception of INT0) can be used to release power-down mode (stop or idle). Interrupts for
power-down mode release are initiated by setting the corresponding interrupt enable flag. Even if the IME flag is
cleared to zero, power-down mode will be released by an interrupt request signal when the interrupt enable flag
has been set. In such cases, the interrupt routine will not be executed since IME = "0".
