3. I/O Mode 
 
 I/O mode 2 (Shared external trigger mode) 
This mode shares the input signals (ECK/TGIN/ TIN) of the base timer between two channels. 
Ta b l e  3 - 8  shows the external pins used when this mode is selected. 
Table 3-8 External pins used when I/O mode 2 is selected.

3. I/O Mode 
 
 If two channels above the channels set to this mode (n+2, n+3) are set to I/O mode 3 (Shared channel signal 
trigger mode)
 , the input signals (ECK/TGIN/TIN) can be input to the 4 channels simultaneously. 
(Example:    If channels 0 and 1 are set to this mode, and channels 2 and 3 are set to I/O mode 3, input 
signals (ECK/TGIN/TIN) can be input to four channels of 0 to 3 simultaneously.)

3. I/O Mode 
 
 I/O mode 3 (Shared channel signal trigger mode) 
This mode inputs the COUT signal from channels below the two channels as a CIN signal, and uses it as 
ECK/TGIN/TIN signals. 
Ta b l e  3 - 11  shows the external pins used when this mode is selected.

3. I/O Mode 
 
 I/O mode 4 (Timer start/stop mode) 
This mode can control the start/stop of the odd channel using the even channel. 
The odd channel starts on the rising edge of output waveform (TOUT signal) of the even channel, and stops 
on the falling edge. 
Table 3-14  shows the external pins used when this mode is selected.

 I/O mode 5 (Software-based simultaneous startup mode) 
This mode starts up multiple channels simultaneously using the Software-based Simultaneous Startup 
Register (BTSSSR). 
All the channels corresponding to  the Software-based Simultaneous Star tup Register (BTSSSR) bits that 
have been set to 1 start up simultaneously. 
Table 3-17  shows the external pins used when this mode is selected.

3. I/O Mode 
 
When 1 is written to a Software-based Simultaneous Startup Register (BTSSSR) bit, a rising edge is input 
(ECK/TGIN/TIN signals) to the channel corresponding to the bit.

3. I/O Mode 
 
 I/O mode 6 (Software-based startup and timer start/stop mode) 
This mode can control the start/stop of the odd channel using the even channel. 
The even channel can be started by writing 1 to  the Software-based Simultaneous Startup Register 
(BTSSSR). 
The odd channel starts when the rising edge is detected in output waveform  (TOUT signal) of the even 
channel, and stops when the falling edge is detected. 
Table 3-20  shows the external pins used when this mode is selected.
