DESCRIPTION
Advanced Tx Control 1:
Advanced Tx Control 0:
Transmitter Power Down:
When high, powers down and tri-states the transmit driver. The transmit
monitor port, if enabled, is also powered down when TXPD is high.
Serial Port Selection:
When high, chip is software controlled through the serial port.
Reference Clock Frequency Selection:
Selects the reference frequency that is supplied at the CKREFP/N pins. Its level
is read in only at power-up or on the rising edge of a reset signal at the PORB
pin.
Float: Normal operation
