10.5. Prescaler
10.6. Timer
On the IO-Panel, there is a region dedicated specially to the SWB, where the Clock
and Data Signals are represented once more (duplicated against the normal Port C
representation).
Additional information available on the IO-Panel is the following:
•
•
•
•
Note : it is important to emphasise that this represented value reflects the
suppression of clocks ; for instance, in the example shown on fig 10-2, although the
buffered data was ‘C,A,B’ , the transmitted data is actually considered to be ‘C,A,3’,
because the last clock is suppressed !
The selected prescaler interrupt frequency is indicated. This corresponds to the
value written to bits 1- 3 in the register 062H.
Mode (Automatic/Interactive)
Clock (external/internal and division factor)
Clock suppression (how many bits are suppressed)
The data being sent: each nibble already sent will appear (from left to right) on
the text box (in hex representation).
