Man_Break
Prototype
void Man_Break();
Description Man_Receive is blocking routine and it can block the program ow. Call this routine from interrupt to
unblock the program execution. This mechanism is similar to WDT.
Parameters None.
Returns Nothing.
Requires Nothing.
Example
char data1, error, counter = 0;
void Timer1Int() org IVT_ADDR_T1INTERRUPT {
if (counter >= 20) {
Man_Break();
counter = 0; // reset counter
}
else
counter++; // increment counter
T1IF_bit = 0; // Clear Timer1 overow interrupt ag
}
void main() {
...
if (Man_Receive_Init() == 0) {
...
}
...
// try Man_Receive with blocking prevention mechanism
IPC0 = IPC0 | 0x1000; // Interrupt priority level = 1
T1IE_bit= 1; // Enable Timer1 interrupts
T1CON = 0x8030; // Timer1 ON, internal clock FCY, prescaler
1:256
data1 = Man_Receive(&error);
T1IE_bit= 0; // Disable Timer1 interrupts
}
Notes Interrupts should be disabled before using Manchester routines again (see note at the top of this
page).
