Screw Terminal Connections
The MC33816 EVB contains four injector outputs, two fuel pump outputs, and one VSUPP input screw
terminal connection.
Figure 5
shows the locations of the screw terminals and their functional definitions:

Pin Jumpers
There are four 3-pin jumper headers on the MC33816 EVB.
1.
VBAT_SELECT
- This is a header to supply the +5.0 V and +3.3 V linear regulator from VSUPP (position 2-3) or
from the VBAT_EXT pin of the EXT_PORT connector (position 1-2).
2.
VCCIO_SEL
- This is a header to Supply VCCIO from the +5.0 V regulator (position 2-3) or from the
VCCIO_EXT pin for the EXT_PORT connector (position 1-2).
3.
DBG_SEL
- This is a header to connect the device DBG pin to the DBG_EXT1 pin of the EXT_PORT connector
(position 2-3) or to the DBG_EXT2 pin of the IO_PORT connector (position 1-2).
4.
CLK_SEL
- This is a header to select the EVB oscillator (position 1-2) or an external clock pin (position 2-3)
applied on the EXT_CLK PIN of the EXT_PORT connector as device clock.
