Timing when 20-bit data is input to IC pins
Timing when 16-bit data is input to IC pins
Use 20-bit input mode when inputting, to the LRCKI, BCKI, and DATAI pins, post-HDCD decoding 20-bit data that
was recorded on MD and using this IC’s internal D/A converter for playback.
When the HDCD filter block input source is set to pin input by setting XDSEL flag to 1, do not set the IC to CD
playback state. In this case, if gain scaling is set to analog gain scaling mode, the GAIN pin will output a low level,
and if set to digital gain scaling mode, it will output a high level.
Clocks applied to the LRCKI and BCKI pins must be synchronized with the LC78628E’s system clock.
HDCD Control Register (CRHDCD)
The HDCD control register consists of 6 flags used for setting the modes associated with HDCD operations. This section
presents the method for setting this register and the meanings of the flags.
Setting procedure
The HDCD control register is set using the following 2-byte command.
Instruction code: $D8xx (2-byte command)
Here, xx corresponds to the flags in CRHDCD, and bits transferred as a high level are set to 1.
