17.5.3
EBR1 specifies the flash memory erase area block. EBR1 is initialized to H'00 when the SWE1
bit in FLMCR 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.
17.5.4
EBR2 specifies the flash memory erase area block. EBR2 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.
Note: These registers are reserved on the HD64F2211 and HD64F2211U. Only H'00 should be
