Functional description

Doc ID 14219 Rev 3

59/64

Buffer data values from $0 to $1F are reserved and not transmitted by the "A" Manchester

data sensor. All "A" satellite sensors use values between $020 and $FFF, therefore values

falls within this range will be interpreted by system software as satellite only data. If a

satellite data is found to be in the range between $00 to $01F the IC asserts the reserved

message error flag or fault code. In case there is no fault condition present, the device

returns $000.

Data is lost when a data word is written to a full buffer. To alarm the user for this condition

the DL (buffer data lost) flag shall be set.
