TS-7250 MANUAL
LEDS, JUMPERS AND BUTTONS
7 LEDS, JUMPERS AND BUTTONS
7.1 Status LEDs
The
TS-7250
has two LEDs (one Red and one Green) available for user software. These
LEDs may be used for diagnostics, status messages, and simple output. When power is
first supplied to the
TS-7250
, both LEDs are immediately turned on under hardware
control. Once the processor begins execution, the LEDs are turned off, and then flashed
on and off again briefly. After booting is complete, these LEDs can be used for user
applications.
The RED and Green LEDs can be controlled at physical address location
0x8084_0020
.
Bit 1 is the RED LED and bit 0 is the Green LED. A Logic “1” turns the LED on.
7.2 Jumpers
The
TS-7250
contains six default jumpers for specific board configuration:
