Refer to the MAX7315 IC data sheet for a detailed I
slave address map.
Jumpers JU3, JU4, JU6, JU8–JU13 set the port config-
urations as described in Table 3.
To use the MAX7315 EV kit with a user-supplied I
interface, install the shunt on jumper JU7 on pins 1 and
2. Connect SDA, SCL, and GND lines from the user-
supplied I
on the MAX7315 EV kit. Apply a 2.0V to 3.6V power
supply to the VCC pad of the MAX7315 EV kit.
Depending on the configuration of the user-supplied
I
pullup resistors R11 and R12.

P7 set as output port, driving LED
D3.
Use P7 pad to evaluate this I/O pin.
P6 set as input port, controlled by
S2.
P6 set as output port, driving LED
D4.
Use P6 pad to evaluate this I/O pin.
INT/O8 set as GPO or interrupt,
driving LED D5.
Use INT/O8 pad to evaluate this I/O
pin.
When P0–P5 are set as output ports,
P0–P5 drive LED D1 and D2. When
P0–P5 are set as input ports, they
are pulled up by VLED.
Use P0–P5 pads to evaluate the
corresponding I/O pin.
