The KEU status register, shown in
outputs. Writing to this location results in an address error being reflected in the KEU interrupt status
register.

describes the KEU status register fields.
KEU Status Register (KEUSR)
Module initialization is nearly the same as software reset, except that the interrupt control register remains
unchanged. This module initialization includes execution of an initialization routine, completion of which is
indicated by the RESET_DONE bit in the KEU status register
0 Don’t reset
1 Reset most of KEU
Software reset.
Functionally equivalent to hardware reset (the RESET signal), but only for KEU. All registers and internal state
are returned to their defined reset state. Upon negation of the SR bit, the KEU enters a routine to perform proper
initialization of the parameter memories. The RD (reset done) bit in the KEU status register indicates when this
initialization is complete
0 Normal operation
1 Full KEU reset

Note: Because the error causing the KEU to stop operating may be masked to the interrupt status register, the

status register is used to provide a second source of information regarding errors preventing normal
operation.
