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.

GEC— Global Exception Clear
This write-only bit negates Global Exception request and clears Global Exception status bits MGE1,
MGE2, ILF1, ILF2 and SCMMISF.

This register is not implemented in some MCUs; see Section 29.2.5.4, ETPUSCMOFFDATAR - eTPU SCM Off-range
Data Register .

Parameter Sign Extension access area, see Section 29.3.2.3, Parameter Access .
3
When the size not the maximum, the unused SCM address range returns the value of the register ETPUSCMOFFDATAR.
4
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.
