12 * Count 0
13 * \__ Synapse 0 -- Signal 0 (Channel A, i.e. TIOA)
14 * \__ Synapse 1 -- Signal 1 (Channel B, i.e. TIOB)
15 * \__ Extension capture0 (RA register)
16 * \__ Extension capture1 (RB register)

18 * It also supports the following events:

20 * Channel 0:
21 * - CV register changed
22 * - CV overflowed
23 * - RA captured
24 * Channel 1:
25 * - RB captured
26 * Channel 2:
27 * - RC compare triggered
