By setting this bit to “1”, the PCM data at the time slot position set by the PCM input buffer 3 time slot selection
register (PCM_ITS3[3:0]) is captured. The capturing of PCM data will start from the next frame in which the
setting of this bit to “1” has been detected. Figure 32 shows the PCM input timing.

By setting this bit to “1”, PCM data is output at the time slot position set by the PCM output buffer 1 time slot
selection register (PCM_OTS1[3:0]). The outputting of PCM data will start from the next frame in which this
bit has been set to “1”. Figure 33 shows the PCM output timing.
