Configuration Pin Muxing
The device provides the user with power-on configuration options which can be set through the use of external pull-up or
pull-down resistors of 4.7 k
on certain output pins (see customer visible configuration pins). These pins are generally used as
output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins while HRESET is
asserted, is latched when PORESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal
function. Careful board layout with stubless connections to these pull-up/pull-down resistors coupled with the large value of the
pull-up/pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured.

Pull-Up Resistor Requirements
The device requires high resistance pull-up resistors (10 k
is recommended) on open drain type pins including I2C pins and
IPIC interrupt pins.
For more information on required pull-up resistors and the connections required for the JTAG interface, see AN3665,
