Registers in Frame 0 support 16-bit and 32-bit accesses.
Missing segments of memory space are reserved and should not be used in applications.
If registers are EALLOW protected, then writes cannot be performed until the EALLOW instruction is executed. The EDIS instruction
disables writes to prevent stray code or pointers from corrupting register contents.
The Flash Registers are also protected by the Code Security Module (CSM).

ACCESS TYPE
Some eCAN control registers (and selected
bits in other eCAN control registers) are
EALLOW-protected.
Not EALLOW-protected
Some eCAN control registers (and selected
bits in other eCAN control registers) are
EALLOW-protected.
Not EALLOW-protected
Some ePWM registers are EALLOW
protected. See

The eCAN control registers only support 32-bit read/write operations. All 32-bit accesses are aligned to even address boundaries.
Missing segments of memory space are reserved and should not be used in applications.
