SCM access is available only when bit VIS=1 on register ETPUMCR, under certain conditions (see Section 29.2.5.1,
ETPUMCR - eTPU Module Configuration Register). SCM can only be written in 32 bit accesses.
29.2.5 System Configuration Registers
29.2.5.1 ETPUMCR - eTPU Module Configuration Register
In the eTPUA/B module, this register is shared between eTPU A and eTPU B engines.. ETPUMCR gathers
configuration and status in the eTPU system, including a Global Exception. It is also used for configuring
the SCM (Shared Code Memory) operation and test.
