21.2
21.2.1
ACTR is the control register for AFEIF and is composed of ACTR1 and ACTR2. ACTR1 is
mainly used for FIFO control commands. ACTR2 is used for AFE control commands and DAA
control commands.
(1) AFEIF Control Register 1 (ACTR1)
Bits 14 to 8, 6, and 5—Reserved
Bit 15—AFE Hardware Control Bit (HC): This bit controls AFE. AFE_HC1 signal is made to
high directly often the next serial transmit data transfer, when this bit is written to 1. Then ACDR
data (AFE control word) is transferred by founding the second AFE.FS. AFEIF module
automatically makes AFE_HC1 signal to low and HC bit to 0, directly after transferring the AFE
control word. See section 21.3.2, AFE Interface for more detail about AFE control sequences.

Description
Normal operation
Digital loop back between Tx FIFO and Rx FIFO is performed. In this time the
transmit data is output to AFE_TXOUT, too.
