21.6.4.1 16-bit MPG Output Data Buffer Register (Upper)
(OPDBRHx)
The 16-bit MPG output data buffer register (upper) (OPDBRHx) selects the pair
of OPDBRHx/OPDBRLx register whose data is to be loaded to the OPDUR/
OPDLR register, and the waveform to be loaded to the OPT5 pin and OPT4 pin.

[bit7:4] BNKF, RDA[2:0]: OPDBRHx/OPDBRLx register select bits
These bits select data in which 16-bit MPG output data buffer register (upper/lower) (OPDBRHx/OPDBRLx)
is to be loaded to the OPDUR/OPDLR register. Data in the 16-bit MPG output data buffer register (upper/
lower) (OPDBRHx/OPDBRLx) selected is to be loaded to the OPDUR/OPDLR register.

[bit3:2] OP5[1:0]: OPT5 output waveform select bits
These bits select the output waveform to the OPT5 pin.
The waveform selected is to be output to the OPT5 pin after the data in the OPDBRHx/OPDBRLx specified
in the BNKF bit and RDA[2:0] bits is loaded to the OPDUR/OPDLR register.
