(3) Output event bus
The output event bus has the underflow signal from each timer connected to it, and is comprised
of four lines of output event bus 0-3. Output event bus signals are connected to output flip-flops,
and can also be connected to other peripheral circuits-output event bus 3 to A-D0 converter,
output event bus 0 to DMA channel 1, and output event bus 1 to DMA channel 2. Furthermore,
output event bus 2 can be connected to input event bus 3.
The table below lists the signals that can be connected to the output event bus.
Table 10.2.3 Signals That Can Be Connected (Fed) to Each Output Event Bus Line
Output Event Bus
Connectable (Acceptable) Signal (Note)
3
TOP8, TIO3, TIO4, or TIO8 underflow signal
2
TOP9 or TIO2 underflow signal
1
TOP7 or TIO1 underflow signal
0
TOP6 or TIO0 underflow signal
Note:
For details about the output destinations of output event bus signals, refer to Figure 10.1.1, "Block
Diagram of MJT."
Timings at which signals are generated to the output event bus by each timer (and those
generated to the input event bus by TIO5, 6) are shown below. (Note that they are generated at
different timings than those forwarded to output flip-flops by timers.)
