Automatic Transmit “All Ones” - Hardware mode
This pin functions as an Automatic Transmit “All Ones”.
TRANSMIT “ALL ONES” PATTERN - HARDWARE MODE” ON PAGE 17.
Interrupt Output - Host mode
This pin goes “Low” to indicate an alarm condition has occurred within the device.
Interrupt generation can be globally disabled by setting the GIE bit to a “0” in the com-
mand control register.
Transmitter Transformer Ratio Select - Hardware mode
The function of this pin is to select the transmitter transformer ratio.
