D[15:14] CaPBTRG[1:0]: Capture B Trigger Select Bits
Selects the trigger edge(s) of the external signal (CAPBx) at which the counter value is captured in the
capture B register.
CAPBTRG[1:0] are control bits for capture mode and are ineffective in comparator mode.
D[13:12] TOuTBMD[1:0]: TOuT B Mode Select Bits
Configures how the TOUT B signal waveform (TOUTBx output) is changed by the compare A and
compare B signals. These bits are also used to turn the TOUT B output On and Off.
TOUTBMD[1:0] are control bits for comparator mode and are ineffective in capture mode.
D[11:10] Reserved
D9 TOuTBinV: TOuT B invert Bit
Selects the TOUT B signal (TOUTBx output) polarity.
1 (R/W): Inverted (active Low)
0 (R/W): Normal (active High) (default)
Writing 1 to TOUTBINV generates an active Low signal (Off level = High) for the TOUT B output.
When TOUTBINV is 0, an active High signal (Off level = Low) is generated.
TOUTBINV is a control bit for comparator mode and is ineffective in capture mode.
