The prescaler contains 3 interrupt sources:
- IRQ32/8 ; this is Ck[6] or Ck[4] positive edge interrupt,
the selection is depending on bit PrIntSel.
- IRQHz1 ; this is Ck[1] positive edge interrupt
- IRQBlink ; this is 3/4 of Ck[1] period interrupt
There is no interrupt generation on reset.
The first IRQHz1 Interrupt occurs 1 sec (32kHz)
after reset.
A possible application for the IRQBlink is LCD-Display
blinking control together with IRQHz1.
