;// TITLE: Disable and Restore INTM and DBGM
|
||
|
|
;//
|
||
|
|
;// Function Prototypes:
|
||
|
|
;//
|
||
|
|
;// Uint16 DSP28x_DisableInt();
|
||
|
|
;// and void DSP28x_RestoreInt(Uint16 Stat0);
|
||
|
|
;//
|
||
|
|
;// Usage:
|
||
|
|
;//
|
||
|
|
;// DSP28x_DisableInt() sets both the INTM and DBGM
|
||
|
|
;// bits to disable maskable interrupts. Before doing
|
||
|
|
;// this, the current value of ST1 is stored on the stack
|
||
|
|
;// so that the values can be restored later. The value
|
||
|
|
;// of ST1 before the masks are set is returned to the
|
||
|
|
;// user in AL. This is then used to restore their state
|
||
|
|
;// via the DSP28x_RestoreInt(Uint16 ST1) function.
|
||
|
|
;//
|
||
|
|
;// Example
|
||
|
|
;//
|
||
|
|
;// Uint16 StatusReg1
|
||
|
|
;// StatusReg1 = DSP28x_DisableInt();
|
||
|
|
;//
|
||
|
|
;// ... May also want to disable INTM here
|
||
|
|
;//
|
||
|
|
;// ... code here
|
||
|
|
;//
|
||
|
|
;// DSP28x_RestoreInt(StatusReg1);
|
||
|
|
;//
|
||
|
|
;// ... Restore INTM enable
