20.5.4  Erase Block Register 2 (EBR2) 
EBR2 specifies the flash memory erase area block. EBR1 is initialized to H'00 when the SWE1 bit 
in FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR1 and 
EBR2 to be automatically cleared to 0.

Bit  Bit Name  Initial Value  R/W  Description 
7, 6  —  All 0  R/W  Reserved 
These bits are always read as 0. The write value should 
always be 0. 
5  EB13  0  R/W  When this bit is set to 1, 64 kbytes of EB13 (H'050000 to 
H'05FFFF) will be erased. 
4  EB12  0  R/W  When this bit is 1, 64 kbytes of EB12 (H'040000 to 
H'04FFFF) will be erased. 
3  EB11  0  R/W  When this bit is set to 1, 64 kbytes of EB11 (H'030000 to 
H'03FFFF) will be erased. 
2  EB10  0  R/W  When this bit is set to 1, 64 kbytes of EB10 (H'020000 to 
H'02FFFF) will be erased.
