oscillator output. Output. The oscout pin is

the output connection for an external crystal

that drives the IA186EB internal Pierce

oscillator. (When an external crystal is used, it

is connected between this pin and the clkin pin.

See clkin table entry.)

Note: If an external oscillator or clock source is

used to drive the IA186EB instead of a crystal,

oscout must be left unconnected (i.e., must

float). When the IA186EB is operating in the

ONCE mode, oscout does not float.
