SELECTIVE SQUELCH AND DISABLE
Each transmitter is equipped with output disable and output
squelch controls. Disable is a full power-down state: the trans-
mitter current is reduced to zero, and the output pins pull up
to VTTO, but there is a delay of approximately 1 μs associated
with re-enabling the transmitter. The output disable control is
accessed through the EN bit (Bit 4) of the OUT_A/OUT_B
configuration registers through the I2C control interface.
Squelch is not a full power-down state but a state in which only
the output current is reduced to zero and the output pins pull
up to VTTO, and there is a much smaller delay to bring back the
output current. The output squelch and the output disable control
can both be accessed through the OUT_A/OUT_B squelch
control registers, with the top nibble representing the squelch
control for one entire output port, and the bottom nibble
representing the output disable for one entire output port. The
ports are disabled or squelched by writing 0s to the corresponding
nibbles. The ports are enabled by writing all 1s, which is the
default setting. For example, to squelch Port A, Register 0xC3
must be set to 0x0F. The entire nibble must be written to all 0s
for this functionality.
