2.7.1 RESET Button
A RESET button is fitted to the front panel to avoid false operation. The RESET button triggers the on-board system reset
generator, as well as the VME if jumper J2 is set.
2.7.2 ABORT Button
Together with the RESET button, an ABORT button is also fitted to the front panel. The ABORT button generates a level
7 IRQ (non-maskable interrupt) which is used for debugging purposes. In this case, bit 1 of the Board Control/Status
Register is not set (remains ‘0’).
2.7.3 LED Port
The front panel LED port consists of three LEDs with the following functions:
Red LED CPU in HALT or RESET status
Yellow LED Watchdog timer running status
Green LED General purpose, set via board control/status register
The green LED is free to be used by the customer. It is set by the software during startup when the 68EN360 is initialized.
