12.0 LINE INTERFACE CONTROL FUNCTION
The DS2143 can control line interface units that contain serial ports. When Control Register Bytes 1 or 2
(CRB1, CRB2) are written to, the DS2143 will automatically write this data serially (LSB first) into the
line interface by creating a chip select, serial clock and serial data via the LI_
CS
, LI_SCLK and LI_SDI
pins respectively. This control function is driven off of the RCLK and it must be present for proper
operation. Registers CRB1 and CRB2 can only be written to, they cannot be read from. Writes to these
registers must be at least 20
μ
s apart. See Section 13 for timing information.
