4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
INTERRUPT STRUCTURE
Interrupt controller:
IL0-IL5
: Interrupt latch . Hold all interrupt requests from all interrupt sources. ILr can not be
set by program, but can be reset by program or system reset, so IL only can decide
which interrupt source can be accepted.
MASK0-MASK3
: MASK register can promit or inhibit all interrupt sources.
EI
: Enable interrupt Flip-Flop can promit or inhibit all interrupt sources, when inter-
rupt happened, EI is cleared to "0" automatically, after RTI instruction happened,
EI will be set to "1" again .
Priority checker: Check interrupt priority when multiple interrupts happened.
INTERRUPT FUNCTION
The procedure of interrupt operation:
1. Push PC and all flags to stack.
2. Set interrupt entry address into PC.
3. Set SF= 1.
4. Clear EI to inhibit other interrupts happened.
5. Clear the IL for which interrupt source has already be accepted.
6. To excute interrupt subroutine from the interrupt entry address.
7. CPU accept RTI, restore PC and flags from stack . Set EI to accept other interrupt requests.
PROGRAM EXAMPLE: To enable interrupt of "TRGA"
LDIA #1100B;
EXAE; set mask register "1100B"
EICIL 111111B ; enable interrupt F.F.
