Bit 4—A/D Trigger Enable (ADTE) (TCSR0 Only): Selects enabling or disabling of A/D
converter start requests by compare match A.
In TCSR1, this bit is reserved: it is always read as 1 and cannot be modified.
Bit 4
ADTE Description
0 A/D converter start requests by compare match A are disabled (Initial value)
1 A/D converter start requests by compare match A are enabled
Bits 3 to 0—Output Select 3 to 0 (OS3 to OS0): These bits specify how the timer output level is
to be changed by a compare match of TCOR and TCNT.
Bits OS3 and OS2 select the effect of compare match B on the output level, bits OS1 and OS0
select the effect of compare match A on the output level, and both of them can be controlled
independently.
Note, however, that priorities are set such that: toggle output > 1 output > 0 output. If compare
matches occur simultaneously, the output changes according to the compare match with the higher
priority.
Timer output is disabled when bits OS3 to OS0 are all 0.
After a reset, the timer output is 0 until the first compare match event occurs.
Bit 3
OS3
Bit 2
OS2 Description
0 0 No change when compare match B occurs (Initial value)
1 0 is output when compare match B occurs
1 0 1 is output when compare match B occurs
1 Output is inverted when compare match B occurs (toggle output)
Bit 1
OS1
Bit 0
OS0 Description
0 0 No change when compare match A occurs (Initial value)
1 0 is output when compare match A occurs
1 0 1 is output when compare match A occurs
1 Output is inverted when compare match A occurs (toggle output)
