Internal Pull- Enables/disables the outputs (OE) or powers down the chip (SD). The SH bit
down
controls the configuration of the SD/OE pin. The SH bit needs to be high for
SD/OE pin to be configured as SD. The SP bit (0x02) controls the polarity of
the signal to be either active HIGH or LOW only when pin is configured as OE
(Default is active LOW.) Weak internal pull down resistor. When configured as
SD, device is shut down, differential outputs are driven high/low, and the
single-ended LVCMOS outputs are driven low. When configured as OE, and
outputs are disabled, the outputs can be selected to be tri-stated or driven
high/low, depending on the programming bits as shown in the SD/OE Pin
Function Truth table.
