EBR1 specifies the flash memory erase block. EBR1 is initialized to H'00 when a high level is
input to the FWP pin. It is also initialized to H'00, when the SWE bit in FLMCR1 is 0 regardless
of value in the FWP pin. Do not set more than one bit at a time in EBR1 and EBR2, as this will
cause all the bits in EBR1 and EBR2 to be automatically cleared to 0.
