Bit 3—Acknowledgement Mode Select (ACK): Selects acknowledgement mode or serial mode.
In acknowledgement mode (ACK = 0), data is transferred in frames consisting of the number of
data bits selected by BC2 to BC0 in ICMR, plus an extra acknowledge bit. In serial mode (ACK =
1), the number of data bits selected by BC2 to BC0 in ICMR is transferred as one frame.

Bits 2 to 0—Serial Clock Select (CKS2 to CKS0): These bits, together with the ICCX bit in the
STCR register, select the serial clock frequency in master mode. They should be set according to
the required transfer rate.
