I
When 16/68# pin is HIGH for Intel bus inter-
face, this input becomes the Reset pin
(active high). In this case, a 40 ns mini-
mum HIGH pulse on this pin will reset the
internal registers and all outputs. The UART
transmitter output will be held HIGH, the
receiver input will be ignored and outputs
are reset during reset period (Table 17).
When 16/68# pin is at LOW for Motorola
bus interface, this input becomes Reset#
pin (active low). This pin functions similarly,
but instead of a HIGH pulse, a 40 ns mini-
mum LOW pulse will reset the internal reg-
isters and outputs.
Motorola bus interface is not available on
the 64 pin package.

Pwr
The center pad on the backside of the QFN
package is metallic and should be con-
nected to GND on the PCB. The thermal
pad size on the PCB should be the approxi-
mate size of this center pad and should be
solder mask defined. The solder mask
opening should be at least 0.0025" inwards
from the edge of the PCB thermal pad.
