3. I/O Mode 
 
 I/O mode 7 (Timer start mode) 
This mode uses the output waveform from the even channel (TOUT signal) as input signals 
(ECK/TGIN/TIN signals) of the odd channel. 
Table 3-23  shows the external pins used when this mode is selected. 
Table 3-23 External pins used when I/O mode 7 is selected.

3. I/O Mode 
 
 I/O mode 8 (Shared channel signal  trigger and timer start/stop mode) 
This mode inputs the COUT signal from channels below the two channels as a CIN signal, and uses it as an 
external startup trigger (TGIN signal). 
Table 3-26 shows the external pins used when this mode is selected.
