SIMS - Master/Slave Mode Selector
0 - Serial audio input port is in slave mode. ISCLK and ILRCK are inputs.
1 - Serial audio input port is in master mode. ISCLK and ILRCK are outputs.
SISF - ISCLK Frequency. Valid only in master mode (SIMS = 1). Should be changed when PDN = 1. See
Table 8 for details.
