CHAPTER 21 MULTI-PULSE GENERATOR
21.5 Operations
21.5.3
Operation of 16-bit MPG Output Data Buffer
Register (Upper/Lower) (OPDBRHx/OPDBRLx)
The 16-bit MPG output data buffer register (upper/lower) (OPDBRHx/OPDBRLx)
are composed of 12 pairs of registers. By loading different OPDBRHx and
OPDBRLx registers into the 16-bit MPG output data register (upper/lower)
(OPDUR/OPDLR), various kinds of waveform are output at the multi-pulse
generator output (OPT5 to OPT0).
■ Operation of Output Data Buffer Register
The data in the 16-bit MPG output data buffer register (upper/lower) (OPDBRHx/OPDBRLx)
whose address specified by the BNKF bit and the RDA[2:0] bits is transferred to the 16-bit
MPG output data register (upper/lower) (OPDUR/OPDLR) at the write timing generated by the
data write control unit.
The BNKF bit and the RDA[2:0] bits in the 16-bit MPG output data buffer register (upper)
(OPDBRHx) decide the order of data transfer to the 16-bit MPG output data register (upper/
lower) (OPDUR/OPDLR), and the OPx1/OPx0 bits decide the shape of the output waveform.
The output waveform is updated automatically as long as the write timing (WTO) is generated.
An example of setting the 16-bit MPG output data buffer register (upper/lower) (OPDBRH,
OPDBRL) is shown in Table 21.5-3.
