12.4.1.2
The key size register reflects 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 256. Specifying a key size outside of this range will cause a key size error (KSE) in the PKEU interrupt
status register.
