Pin Function
Power supply input for digital functions.
Open-drain output. Can be selected (via OEMCFG3 bit 7) to be an open-drain GPO or an active-
low, open-drain, pulsed reset signal output controlled by the status of bits [0-2] of byte A2h: FFh.
Ground return for digital functions.
Digital input. Receiver Rate Select input. OR’ed with soft rate select bit SRS0 to determine the
state of the RRSOUT pin. The state of this pin is always reflected in the RS0S bit.
If bit 4 (IE) in the USRCTL register is set to 0 (its default value), this pin is configured as an analog
input. If IE bit is set to 1, this pin is configured as an open-drain output.
Analog input: Multiplexed A/D input for monitoring supply voltage, with a 0V to 5.5V input range.
Open-drain output: outputs the internally generated active-low interrupt signal /INT.
Digital input. Serial clock input.
Digital I/O, open-drain, bi-directional serial data input/output.
Digital input; Active high. The transmitter is disabled when this input is high or the STXDIS bit is
set to 1. The state of this input is always reflected in the TXDIS bit.
Digital Output; Open-Drain, with programmable polarity. If OEMCFG5 bit 4 is set to 0, a high level
indicates a hardware fault impeding transmitter operation. If OEMCFG5 bit 4 is set to 1, a low level
indicates a hardware fault impeding transmitter operation. The state of this pin is always reflected
in the TXFLT bit.
Digital Input; Transmitter Rate Select Input; OR’ed with soft rate select bit SRS1 to determine the
state of the TRSOUT pin. The state of this pin is always reflected in the RS1S bit.
Analog Input. Multiplexed A/D converter input for monitoring received optical power. The input
range is 0 to V
ranging of the RX power measurement.
