26.5.6 PKEU Registers
26.5.6.1 PKEU Mode Register (PKEUMR)
PKEUMR specifies the internal PKEU routine to execute. PKEUMR is cleared when the PKEU
is reset or reinitialized. Setting a reserved mode bit generates a data error. If the Mode Register is
modified during processing, a context error is generated. Table 26-24 describes the PKEUMR
fields.
