10.7.7.1
This register specifies the internal PKEU routine to be executed. The mode register is cleared when the
PKEU is reset or re-initialized. Setting a reserved mode bit generates a data error. If the mode register is
modified during processing, a context error is generated.
For channel-controlled access to the PKEU, the descriptor type is determined by the ROUTINE to be used.
The descriptor type used with each ROUTINE is listed in
10.7.7.2
The key size register specifies the number of significant bytes to be used from PKEU Parameter Memory
E in performing modular exponentiation or elliptic curve point multiplication. The range of values for this
register, when performing either modular exponentiation or elliptic curve point multiplication, is from 1 to
512. Specifying a key size outside of this range causes a key size error (KSE) in the PKEU interrupt status
register.
