Test
Test Mode – When pulled logic Low and then applying power or resetting, the trans-
ceiver’s serial interface is forced to a 9600, 8-N-1 rate. To exit Test mode, the trans-
ceiver must be reset or power-cycled with Test Mode pulled logic High or left
floating/disconnected.

floating/disconnected.
Note: Because this mode disables some modes of operation, it should not be perma-
nently pulled Low during normal operation.

UP_Reset
RESET – Controlled by the LT2510 for power-on reset if left unconnected. After a sta-
ble power-on reset, a logic Low pulse will reset the transceiver.

CMD/Data
When logic Low, the transceiver interprets OEM Host data as command data. When
logic High, the transceiver interprets OEM Host data as transmit data.
