[Source for setting this bit to 1]
When the value in the TRDi register
matches w ith the value in the TRDGRAi
register.
Input capture/compare match flag B [Source for setting this bit to 0]
Write 0 after read.
(2)
[Source for setting this bit to 1]
When the value in the TRDi register
matches w ith the value in the TRDGRBi
register.

Nothing is assigned. If necessary, set to 0.
When read, the content is 1.
The writing results are as follow s:
• This bit is set to 0 w hen the read result is 1 and w riting 0 to the same bit.
• This bit remains unchanged even if the read result is 0 and w riting 0 to the same bit. (This bit remains 1 even if this
bit is set to 1 from 0 after reading, and writing 0.)
• This bit remains unchanged w hen w riting 1.
