The system status is an 8-bit number which can take one of the following
values:
0 System normal (no detected errors).
1 A processor reset occurred. This code is only present
transitorily.
2 Serial communications error. This is most likely to be caused
by a message being sent to the Free-d unit before the reply to the
previous message has been received.
3 Vertical blanking failure. This may indicate a hardware fault,
or a problem with the digital video input.
4 Xilinx failure. The programmable logic devices have not
initialised correctly; if persistent, this indicates a hardware
fault.
5 I2C bus failure. Communication between the CPU and peripheral
devices has failed, indicating a probable hardware fault.
6 EEPROM failure. An attempt to save the parameters to non-
volatile memory U3 has failed, indicating a probable hardware
fault.
7 DSP failure (1). The DSP failed to acknowledge a command; if
persistent, this indicates a hardware fault.
8 DSP failure (2). The DSP failed to accept data; if persistent,
this indicates a hardware fault.
9 DSP failure (3). The DSP failed to provide data; if
persistent, this indicates a hardware fault.
10 DSP failure (4). The DSP is flagging an exception error; if
persistent, this indicates a hardware or software fault.
91 I2C communication failure: No Reply.
93 I2C communication failure: Bus Error.
94 I2C communication failure: ACK Error.
95 I2C communication failure: Undefined State.
96 I2C communication failure: Overflow.
The ‘I2C communication failure’ codes result from a problem with
communication between the processor and the I2C peripherals U3 and U17,
most likely indicating a hardware fault.
