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.
