Symmetric Key Hardware Accelerator (SKHA)
28.2.1.6 SKHA Error Status Mask Register (SKESMR)
The SKESMR (located at address IPSBAR + 0x1B_0014) allows the user to mask off any of the
SKHA Error bits and not generate an interrupt. If the error occurs while the corresponding bit is
set then the error will be set in the SKESR but the interrupt will not be generated. Additional errors
will be flagged in the SKESR until an unmasked error is generated.
