6.3.2. Serial Setup Port (SSP)
As for the SSP block, it is used to configure the 4 x 9 bits control registers in the software mode, or is
used to setup some functions such as mute and de-emphasis in the hardware mode. The
performance of digital de-emphasis filter is shown in Figure 6-4. It illustrates the de-emphasis
frequence response and corresponding to the de-emphasis error for 32K, 44.1K, and 48 KHz. In this
device, user can make advtantage of the MODE pin to select the software mode or the hardware
mode. When the hardware mode is selected, the DINLR input data format is only choosed by the 16-
bit normal data format. If more functions than one in the hardware mode must be generated by this
chip, it must be setup control registers via SSP port whose timing shown in Figure 6-7. In the Figure
6-4, the first 5 bit are reserved bits (res) and must be logic-zero. Next 2 bits are address bits, A1 and
A0 bit, to select the 4 control registers. For example, if A1 = 0 and A0 = 1, the second register will be
configured. The final 9 bits, B8--B0, are data configuration bits. The setup of control registers refers to
section 7, Control Registers. Many functions such as the 256 setp attenuation for the left and right
channel, digital de-emphasis filter, zero detection, soft mute, input format selection, channel control,
can be programmed by 4 x 9 registers in the software mode.
