block can be erased. Other blocks are erase-protected. Only one of the bits of EBR1 and EBR2
combined can be set. Do not set more than one bit. (Do not set more than one bit, as this will
automatically clear both EBR1 and EBR2 to 0.) When on-chip flash memory is disabled, a read
will return H'00, and writes are invalid.
The flash memory block configuration is shown in table 20.5.
