When the INV01 bit is set to "0" (the ICTB2 counter
increments whenever the timer B2 counter underflows)
and the setting value is n, the timer B2 interrupt is
generated every nth time timer B2 counter underflow
occurs.
When the INV01 bit is set to "1" (selected by the INV00
bit) and setting value is n, the timer B2 interrupt is
generated every nth time timer B2 counter underflow
meeting the condition selected in the INV00 bit occurs.
If setting value is n, the timer stops when the nth count
source is counted after a start trigger is generated.
Positive phase changes to negative phase, and vice
versa, when the timers A1, A2 and A4 stop.
