INV00 to INV07: bits in the INVC0 register
INV10 to INV15: bits in the INVC1 register
DVi, DVBi: bits in the IDBi register (i = 0, 1)
PWCON: bit in the TB2SC register
NOTE:
1. When the INV06 bit is set to 0 (triangular wave modulation mode), a transfer trigger is generated at the first timer B2
underflow after writing to the IDBi register (i = 0, 1).
