host.
Bit 6-
nLoopBack
– “1” disables loopback of HDI to HDO.

SIG60 Configuration
The SIG60 operates at default with the following parameters:
Bit rate: 19.2 kbps, F0=5.5MHz, F1=6.5MHz
The following configuration bits set the operating frequencies according to table 4.2.

Command Mode
When in command mode, the host can configure the device according to the desired operating
parameters. The device enters command mode when pin HDC is lowered to “0”. When in command
mode, data on the HDI pin is not transmitted to the bus, but is used to configure the SIG60. The
command can be written in any of the allowed Bit Rates.
In order to write to a control register, the host sends two bytes. The first byte begins with the address of
the register followed by 5(hex). The second byte is the configuration data, as shown in figure 4.1. The
bytes should be sent more than 200nSec after lowering HDC.
