EBR1 and EBR2 are used to specify the flash memory erase block. EBR1 and EBR2 are
initialized to H'00 by a reset, or in hardware standby mode, software standby mode, sub-active
mode, sub-sleep mode, or watch mode, or when the SWE bit in FLMCR1 is cleared to 0. Set only
one bit to 1 at a time, otherwise all bits in EBR1 and EBR2 are automatically cleared to 0.
