Serial Port Clocking
The CS43L22 serial audio interface port operates either as a slave or master, determined by the M/S bit. It
accepts externally generated clocks in Slave Mode and will generate synchronous clocks derived from an
input master clock (MCLK) in Master Mode. Refer to the tables below for the required setting in register 05h
and 06h associated with a given MCLK and sample rate.
