Data Sheet
SDLC COMMUNICATIONS CONTROLLER
Diagnostics
A diagnostic mode is included with the IA8044/IA8344 to allow testing of the SIU. Diagnostics use
port pins P3.0 and P3.1. Writing a 0 to P3.1 enables the diagnostic mode. When P3.1 is cleared
writing data to P3.0 has the effect of writing a serial data stream to the SIU. P3.0 is the serial data
and any write to port 3 will clock SCLK. The transmit data may be monitored on P3.1 with any
write to port 3 again clocking SCLK. In the test mode P3.0 and P3.1 pins are placed in the high
impedance state.
