ColdFire Flash Module (CFM)
6.3.4
The Flash registers are described in this subsection.
6.3.4.1
The CFMCR is used to configure and control the operation of the CFM array.
Bits 10 -5 in the CFMCR register are readable and writable with restrictions.

S = Supervisor access only. User mode accesses to supervisor only addresses have no effect and result in a
cycle termination transfer error.
Addresses not assigned to a register and undefined register bits are reserved for expansion. Write accesses
to these reserved address spaces and reserved register bits have no effect.

Reserved, should be cleared.
Write lock control. The LOCK bit is always readable and is set once.
1 CFMPROT, CMFSACC, and CFMDACC register are write-locked.
0 CFMPROT, CMFSACC, and CFMDACC register are writable.
Protection violation interrupt enable. The PVIE bit is readable and writable. The
PVIE bit enables an interrupt in case the protection violation flag, PVIOL, is set.
1 An interrupt will be requested whenever the PVIOL flag is set.
0 PVIOL interrupts disabled.
Access error interrupt enable. The AEIE bit is readable and writable. The AEIE bit
enables an interrupt in case the access error flag, ACCERR, is set.
1 An interrupt will be requested whenever the ACCERR flag is set.
0 ACCERR interrupts disabled.
