Reset Value: 0000 0000 (00h)
Bit 7 = OPE: Output Port Enable.
This bit can be set by software only if the NMI bit is
cleared.
0: Output port is in high impedance (without pull-
1: Output port is available for data transfer.
Bit 6 = ODS: Output Data Selection.
0: Dead time generator data.
1: Select the Bit 5:0 data
Bit 5:0 = Uh, Ul, Vh, Vl, Wh, Wl phases
These bits can be sent out through the output port.
