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.
port 1, Bit [N] (N = 0–7). Output. Each pin of
Port 1, p1.0–p1.7, can function individually as a
general-purpose output line.
port 2, Bit [0]. Input/Output. This pin functions
as a general-purpose I/O line.
port 2, Bit [1]. Output. This pin functions as a
general-purpose output line.
port 2, Bit [2]. Input. This pin functions as a
general-purpose input line.
port 2, Bit [3]. Output. This pin functions as a
general-purpose output line.
port 2, Bit [4]. Input. This pin functions as a
general-purpose input line.
port 2, Bit [5]. Input. This pin functions as a
general-purpose input line.
port 2, Bit [6]. Input/Output (open drain). This
pin functions as a general-purpose bidirectional
input/output line.
port 2, Bit [7]. Input/Output (open drain). This
pin functions as a general-purpose bidirectional
input/output line.
