19.5.3  Erase Block Register 1 (EBR1) 
EBR1 specifies the flash memory erase area block. EBR1 is initialized to H'00 when the SWE bit 
in FLMCR1 is 0. Set only one bit in EBR1 and EBR2 together (do not set more than one bit at the 
same time. Setting more than one bit will automatically clear all EBR1 and EBR2 bits to 0). For 
details, see table 19.3. 
Bit  Bit Name  Initial Value  R/W  Description 
7  EB7  0  R/W  When this bit is set to 1, 4 kbytes of EB7 are to be 
erased. 
6  EB6  0  R/W  When this bit is set to 1, 4 kbytes of EB6 are to be 
erased. 
5  EB5  0  R/W  When this bit is set to 1, 4 kbytes of EB5 are to be 
erased. 
4  EB4  0  R/W  When this bit is set to 1, 4 kbytes of EB4 are to be 
erased. 
3  EB3  0  R/W  When this bit is set to 1, 4 kbytes of EB3 are to be 
erased. 
2  EB2  0  R/W  When this bit is set to 1, 4 kbytes of EB2 are to be 
erased. 
1  EB1  0  R/W  When this bit is set to 1, 4 kbytes of EB1 are to be 
erased. 
0  EB0  0  R/W  When this bit is set to 1, 4 kbytes of EB0 are to be 
erased. 
19.5.4  Erase Block Register 2 (EBR2) 
EBR2 specifies the flash memory erase area block. EBR2 is initialized to H'00 when the SWE bit 
in FLMCR1 is 0. Set only one bit in EBR2 and EBR1 together (do not set more than one bit at the 
same time. Setting more than one bit will automatically clear all EBR1 and EBR2 bits to 0). For 
details, see table 19.3.
