Man_Break
Prototype
sub procedure Man_Break()
Description Man_Receive is blocking routine and it can block the program flow. Call this routine from interrupt to 
unblock the program execution. This mechanism is similar to WDT.
Parameters None.
Returns
Nothing.
Requires
Nothing.
Example
dim data1, error, counter as byte
sub procedure Timer1Int() org IVT_ADDR_T1INTERRUPT
  counter = 0
  if (counter >= 20) then
    Man_Break()
    counter = 0                ‘ reset counter
  else
    Inc(counter)               ‘ increment counter
  end if
  T1IF_bit = 0                 ‘ Clear Timer1 overflow interrupt flag
end sub
main:
  ...
  if (Man_Receive_Init() = 0)
    ...
  end if
  ...
  ‘ try Man_Receive with blocking prevention mechanism
  IPC0 = IPC0 or 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
end.
Notes
Interrupts  should  be  disabled  before  using  Manchester  routines  again  (see  note  at  the  top  of  this 
page).
