（note） Input level of REC is relative to AVDD.
（note） Output level of PB is relative to AVDD.
（note） Input impedance oｆ BEEPIN is changed to 20kΩ～163kΩ by BVOL.
（note） Output level 3.0dBV of SPPOS/SPNEG is about 250mW at RL=8Ω.
Control commands are entered on the SEN, SCLK, and SDATA pins, using 3 line 16 bit serial input (MSB first).
The input cycle is started on the CSB falling edge, and each bit of data is read in on the SCLK rising edge.
The data is loaded to register on the CSB rising edge.
