3.5.9. Software Flow for Interrupt driven STATUS
Check
A detailed software flow diagram is shown in Fig. 3–2
on page 46.
If the D_CTR_I/O_1 pin of the MSP 34x1G is con-
nected to an interrupt input pin of the controller, the fol-
lowing interrupt handler can be applied to be automati-
cally called with each status change of the
MSP 34x1G. The interrupt handler may adjust the TV
display according to the new status information.
Interrupt Handler:
<80 11 02 00 <81 dd dd> // Read STATUS
// adjust TV display with given status information
// Return from Interrupt
