If a bus error occurs, the corresponding bus error interrupt
is always forced, if enabled. At the same time, the current
position of the bit stream processor is captured into the
error code capture register. The content within this register
is fixed until the users software has read out its content
once. The capture mechanism is then activated again.
The corresponding interrupt flag located in the interrupt
register is cleared during the read access to the interrupt
register. A new bus error interrupt is not possible until the
capture register is read out once.

(EWLR)
The error warning limit can be defined within this register.
The default value (after hardware reset) is 96. In reset
mode this register appears to the CPU as a read/write
memory. In operating mode it is read only.
Note, that a content change of the EWLR is only possible,
if the reset mode was entered previously. An error status
change (see status register; Table 14) and an error
warninginterruptforcedbythenewregistercontentwillnot
occur until the reset mode is cancelled again.
