8 The LEDs
8.1 The Status LEDs D4 and D5
The kitCON-161CS/JC/JI is fitted with two LEDs D4 and D5, which
indicate the status of the board.
The red LED D4 simply indicates proper connection to the power
source.
The green LED D5 gives the status of the initialization of the control-
ler done by software. At the end of the basic initialization in any pro-
gram a ’EINIT’ command should be executed. Following execution of
this command the SYSCON-register is protected and can not be
changed accidentally. The green LED D5 lights up after this com-
mand is executed to indicate the end of the basic initialization (see the
’Instruction Set Manual’ for further information about ’EINIT’).
These LEDs are automatically controlled by hardware.
8.2 General Purpose LEDs D6 - D13 at Port P2
In addition to the status LEDs the kitCON-161CS/JC/JI is equipped
with 8 red LEDs at D6 - D13. These are connected to Port P2.15 to
P2.8 and can be controlled by software. Writing a low-level to one of
the ports will activate the corresponding LED.
The general purpose LEDs D6-D13 can only be activated by a user-
application.
