Note: Using a PCM interface as a speech codec interface is not currently supported; therefore, ITS2a, ITS3a, ITS2b
and ITS3b cannot be used. If it is necessary to use a PCM interface as a speech codec interface, contact our sales
personnel.
(4) Output Time Slot Selection Method
• PCM Signal Output Pin for CH0a/CH1a (PCMO_a)
Note:
Note that if a PCM interface is selected for both a front end interface and a speech codec interface, the PCM output
signal of each interface will be output using to the upper 8 bits and lower 8 bits of one time slot.
For each of the buffers, time slot and enable/disable settings can be made individually using the following setting
method.
<Setting Method>
1) Select TS#1 to TS#16 with the PCMa output buffer n setting register (PCM_OTSn[3:0]_a: n=0 to 3).
2) The output of the PCM data at the applicable time slot position will be started by setting the PCMa output buffer
OKI Semiconductor
The PCM data to be output from PCMO_a can be output to up to two time slots with the two buffers (16-bit width)
PCMOa ouptut buffer 0 (OTS0a) and PCMOa output buffer 1 (OTS1a). These two buffers are assigned to output
the PCM signals described below. (See also the Block Diagram of this LSI.)
Note that PCM data is output using the upper 8 bits or lower 8 bits selected by the PCMa output buffer n
upper/lower selection register (OTSn_SEL_a), and the unselected 8 bits will be FFh (Hi-Z) output.
n enable control register (PCMOn_EN_a; n = 0 to 3) to “1”.
Furthermore, specify either upper 8 bits or lower 8 bits of 16-bit width with the PCMa output buffer n upper/lower
selection register (OTSn_SEL_a).
− PCMOa output buffer 0 (OTS0a)
− PCMOa output buffer 1 (OTS1a)
If a PCM interface is selected as a front end interface, the PCM signal for CH0a is output. Additionally, if a
PCM interface is selected as a speech codec interface, the PCM signal for CH0a is output.
If a PCM interface is selected as a front end interface, the PCM signal for CH1a is output. Additionally, if a
PCM interface is selected as a speech codec interface, the PCM signal for CH1a is output.
