TABLE 1-1:
1.5.1
The Receive Data Output pin is a open drain (OD)
output and follows the state of the LIN pin.
1.5.2
Chip Select Input pin. An internal pull-down resistor will
keep the CS pin low. This is done to ensure that no
disruptive data will be present on the bus while the
microcontroller is executing a Power-on Reset and an
I/O initialization sequence. The pin must detect a high
level to activate the transmitter.
If CS = 0 when the V
stays in Ready mode. In Ready mode, the receiver is
on and the LIN transmitter driver is off.
If CS = 1 when the V
will proceed to the Operation mode as soon as internal
voltages stabilize.
This pin may also be used as a local wake-up input
(Refer to
microcontroller I/O controlling the CS should be
converted to a high-impedance input allowing the
internal pull-down resistor will keep CS low. An external
switch, or other source, can then wake-up both the
transceiver and the microcontroller (if powered).

It is not recommended to tie CS high as
this can result the MCP2003/4 entering
Operation mode before the microcon-
troller is initialized and may result in
unintentional LIN traffic.

1.5.3
This pin is only available on the MCP2003.
The WAKE pin has an internal 800K pull up to V
falling edge on the WAKE pin causes the device to
wake from Power-Down mode. Upon waking, the
MCP2003 will enter Ready mode
1.5.4
This pin is only available on the MCP2004. This pin is
bidirectional and allows disabling of the transmitter, as
well as fault reporting related to disabling the
transmitter. This pin is an open-drain output with states
as defined in
whenever this pin is low (‘0’), either from an internal
Fault condition or by an external drive. While the
transmitter is disabled, the internal 30 k pull-up
