NOTES:

1 On the 176 LQFP package options the Nexus pins are multiplexed with other GPIO. On the 208 TEPBGA package,

there are additional dedicated Nexus pins.

NOTES:

1 The dedicated (208 pin package only) Nexus output pins (Message Data outputs 0:3 [MDO] and Message Start/End

outputs 0:1 [MSEO]) may drive an unknown value (high or low) immediately after power up but before-the 1st clock

edge propagates through the device (instead of being weakly pulled low). This may cause high currents if the pins

are tied directly to a supply/ground or any low resistance-driver (when used as a general purpose input [GPI] in the

application).
