19.16.2 Flash Memory Control Register 2 (FLMCR2)
FLMCR2 is an 8-bit register that controls the flash memory operating modes. FLMCR2 is initialized to H'00 by a reset,
and in hardware standby mode and software standby mode.
When on-chip flash memory is disabled, a read will return H'00 and writes are invalid.
Bit 7—Flash Memory Error (FLER): Indicates that an error has occurred during an operation on flash memory
(programming or erasing). When FLER is set to 1, flash memory goes to the error-protection state.
Bits 6 to 0—Reserved: These bits cannot be modified and are always read as 0.
19.16.3 Erase Block Register 1 (EBR1)
EBR1 is an 8-bit register that specifies the flash memory erase area block by block. EBR1 is initialized to H'00 by a reset,
in hardware standby mode and software standby mode, and the SWE bit in FLMCR1 is not set. When a bit in EBR1 is set,
the corresponding block can be erased. Other blocks are erase-protected. Set only one bit in EBR1 and EBR2 together
(setting more than one bit will automatically clear all EBR1 and EBR2 bits 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 19-33.
