9.4 J3 External Control
The following connector, see Table 9-3 , is appointed as the external control of the MC33912 device. The choice between
on-board control through the MCU, or external control, is made through Jumpers JP10 - JP20.
Table 9-3. External Control Pin Description
Terminal Terminal Name Definition
1 LINRXD This terminal is the receiver output of the LIN
interface which reports the state of the bus
voltage to the MCU interface.
2 LINTXD This terminal is the transmitter input of the LIN
interface which controls the state.
3 MISO SPI (Serial Peripheral Interface) data sent to the
controller by the MC33912.
4 MOSI SPI (Serial Peripheral Interface) data received by
the MC33912.
5 SCLK SPI (Serial Peripheral Interface) clock input.
6 CS SPI (Serial Peripheral Interface) control chip
select input terminal.
7 PGND Power ground.
8 PWMIN High Sides and Low Sides Pulse Width
Modulation Input.
9 RST Reset I/O terminal. This is bidirectional allowing a
reset of the entire system. It is driven low when
any internal reset source is asserted.
10 IRQ Interrupt output terminal, indicating wake-up
events from Stop Mode or events from Normal
and Normal Request Modes.
11 AGND Analogue ground.
12 AGND Analogue ground.
13 ADOUT1 Current sense analogue output.
14 ADOUT0 Analogue multiplexer output.
9.5 CON1 LIN Bus Connector
The LIN bus terminal provides a physical layer for single wire communication in automotive applications. The LIN terminal is
optionally attached to the LIN physical interface device (place Jumper JP205).
Table 9-4 shows the three pin connector standard
definition.
