• Description: Renesas 32-bit Risc Microcomputer Superhtm Risc Engine Family Sh-4a Series
• Manufacturer: Renesas Electronics Corporation.

Note: In the figure, only the shaded areas are transmitted or received as valid data. Therefore,
Monaural or stereo can be specified for transmit data by the TDLE bit and TDRE bit in SITDAR.
Monaural or stereo can be specified for receive data by the RDLE bit and RDRE bit in SIRDAR.
To achieve left and right same audio output while stereo is specified for transmit data, specify the
TLREP bit in SITDAR. Table 29.8 and table 29.9 show the audio mode specification for transmit
data and that for receive data, respectively.

Left and right same audio output
access must be made in byte units for 8-bit data, and in word units for 16-bit data. Data in
unshaded areas is not transmitted or received.
(a) 16-bit stereo data
(b) 16-bit monaural data
(c) 8-bit monaural data
