Oscillator and Clock Signals
OSCI
3
I
Oscillator input. Input to the on-chip crystal oscillator. When a
crystal is used, it should be connected across pins OSCI and
OSCO. If a crystal clock oscillator or external clock source is
used, then OSCI should be connected to the clock source and
OSCO left open. The external clock source (or crystal clock
oscillator) should have a 50
±
0.25% duty cycle and
±
50 ppm
accuracy.
OSCO
2
O
Oscillator output. Output from the on-chip crystal oscillator.
Should be connected to one side of a crystal or left open if an
external clock source or crystal clock oscillator is used.
OSCF
75
O
Buffered oscillator output. Inverted buffered output of the on-chip
crystal oscillator output.
OSCEN
12
I
Oscillator enable. Enables the on-chip crystal oscillator when
asserted; otherwise, the on-chip crystal oscillator is disabled.
OSCUP
47
O
Microprocessor clock. This is a clock signal generated internally
from the master oscillator; it is the divide-by-4 version of the
master oscillator. For example, when a 16.384 MHz master
oscillator is used the OSCUP pin delivers a 4.096 MHz clock.
The main purpose of OSCUP is to reduce the number of clock
signals required for the system.
Voice/Data Port Signals
The voice/data port signals can be divided into the following three categories:
1. General control
control signals that configures the W9310
2. Handshaking
modem interface signals in data mode
3. Data I/O
data input and output from the W9310
General Control Signals
DAT
32
I*
Data select. Selects data or voice operation. The W9310
operates in data mode when DAT is set to high (binary "1"), and
in voice mode when it is low (binary "0"). Default condition is
voice mode (pull-down on the input).
