7.2.3
EBR1 specifies the flash memory erase area block. EBR1 is initialized to H'00 when the SWE bit
in FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR1 to
be automatically cleared to 0.
7.2.4
Bit 7 (FLSHE) in FENR enables or disables the CPU access to the flash memory control registers,
FLMCR1, FLMCR2, and EBR1.
