5.2.2 Functional description
The manufacturer error block is executed with the rising edge of the
REQ
input.
The
VALID,
ERROR, ERRVAL, STATUS
and
TR_Manuf_Error
outputs are
reset to 0. The
BUSY
output is set to 1.
The asynchronous read access to the measuring system is then executed. The
data of index 0xE00C are read.
The time for resetting the
REQ
input to 0 has no influence on the asynchronous
read access.
As soon as the read access is ended, the
BUSY
output is reset to 0 again.
Depending on whether the read access was successful and no other errors have
been detected, the
VALID
output is set to 1 or, in the case of error, the
ERROR
output is set to 1.
If the read access was successful and a manufacturer-specific error has been
read, this is output at the
TR_Manuf_Error
output. Otherwise the
TR_Manuf_Error
output has the value 0. Reading of a manufacturer-specific
error is also indicated via the
STATUS
output.
If the read access was unsuccessful, the error can be determined via the
STATUS
output. In the case of a read error due to the RDREC block, the error value of the
block is also indicated at the
ERRVAL
output.
