Registers

The registers that are controlled via the serial interface are shown in Table 6.

Table 6

Register map

6.5.1

The serial interface channel programming word is forwarded to the UAA3558 3-wire interface. The channel information

cannot normally be used directly and needs a conversion to get the right number for the UAA3558.

BIT

DESCRIPTION

7

If trx = 0, then device in Transmit mode. If trx = 1, then device in Receive mode.

6 to 0

These 7 bits determine the channel number (m).
