Halting TCD and Waiting for SW Restart Does Not Work if Compare Value A is ‘0’ or Dual Slope Mode is Used

Halting TCD and waiting for software restart (INPUTMODE in TCDn.INPUTCTRLA is ‘0x7’) does not work if compare value A is 0 (CMPASET in TCDn.CMPASET is ‘0x0’) or Dual Slope mode is used (WGMODE in TCDn.CTRLB is ‘0x3’).

Work Around

Configure the compare value A (CMPASET in TCDn.CMPASET) to be different from ‘0’ and do not use Dual Slope mode (WGMODE in TCDn.CTRLB is not ‘0x3’).
