DT Instant interups - interupt while executing an interupt routine question

[Darrel Taylor]

You got it!
That's what will happen.
And the order they are executed will depend on the order in the INT_LIST.

For instance ...
With the INT_LIST below ..., INT_INT will be the first handler executed, if it's flag is set.
Then it will do TMR0_INT next (if flagged).
If another INT_INT happens while it's in TMR0_INT, then it will wait until TRM1_INT has also finished before it goes back around and handles INT_INT again.

ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler    INT_INT,  _ToggleLED1,   PBP,  yes
        INT_Handler   TMR0_INT,  _ToggleLED2,   PBP,  yes
        INT_Handler   TMR1_INT,  _ClockCount,   PBP,  yes
    endm
    INT_CREATE                ; Creates the interrupt processor
ENDASM

If the INT_INT really can't wait for TMR1_INT then you can add another INT_INT handler in-between so that it won't have to wait.

ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler    INT_INT,  _ToggleLED1,   PBP,  yes
        INT_Handler   TMR0_INT,  _ToggleLED2,   PBP,  yes
        INT_Handler    INT_INT,  _ToggleLED1,   PBP,  yes
        INT_Handler   TMR1_INT,  _ClockCount,   PBP,  yes
    endm
    INT_CREATE                ; Creates the interrupt processor
ENDASM

It still calls the same handler for both of them.
