NOTE:
1. If the INV06 bit is set to 0 (triangular wave modulation mode), a transfer trigger is generated at only the first occurrence of a timer B2 underflow after writing to the IDB0 and IDB1 registers.
Set to 0 when TA2S bit is set to 0
Set to 0 when TA1S bit = 0
Set to 0 when TA4S bit is set to 0
