DEMOEM User Manual
EEPROM Enable
LED Display Port
J15 - LED Display Enable Port Port 1 LED_ENABLE1
The DEMOEM includes a serial SPI memory for non-volatile data storage.
Header J14 configures control signals for the EEPROM IC (U4).
The DEMOEM has 4 LEDs connected to signals PTE4, PTE5, PTA5, and
PTA6 that may be driven by 5V. They can be enabled or disabled by installing
or removing the corresponding jumpers, J15 & J41, in the LED_EN header.
Enables port connections PTE5 and PTE4 to LED circuits. This is the default
setting.
