SCLKDIV[0:7]
Bit 0-7 Number of bits per frame
Bits per frame = BPF[0:7] + 1. (max. 256 bits/frame)
Bit 8-15 Serial clock divider
On master mode,the SCLK is an output and its frequency is
SCLK frequency = EXTCLK / (2*(SCLKDIV+1))
Control Register (CTRL)

Bits 0
This is a self-clear bit, ie. set this bit to 1, it will be clear to 0 automatically after 1 EXTCLK.
When this bit is set, all registers will be set to its default value and the controller will be also
set to its initial states.
Device reset
Bit 1
This is a self-clear bit, ie. set this bit to 1, it will be clear to 0 automatically after 1 EXTCLK.
When this bit is set, The TX-FIFO pointer will be cleared to 0, the TX-FIFO is empty
immediately.
Reset TX-FIFO
Bit 2
This is a self-clear bit, ie. set this bit to 1, it will be clear to 0 automatically after 1 EXTCLK.
When this bit is set, The RX-FIFO pointer will be cleared to 0, the RX-FIFO is empty
immediately.
Reset RX-FIFO
