Circuit-, IC descriptions and list of abbreviations
9.
9.5.6
On/Off
The digital board is not powered in standby mode. Control
signal ION, coming from the analog board, will enable the PSU
and power the digital board.
•
ION = High: the digital board is in powered down standby
mode
•
ION = Low: the power supply to the digital board is enabled
9.5.7
Reset
Control signal IRESET_DIG, controlled by the microprocessor
on the analog board is sent to the RESET LOGIC circuit.
•
IRESET_DIG = Low in standby mode
•
IRESET_DIG = High: the whole system is reset and the
Digital board is waked up.
9.5.8
