* This routine initializes the 908AS60 before calling the erasing routine,
* EraseRoutine. If a user plans to incorporate EraseRoutine into his/her
* program, make sure the FLASH control registers and the FLASH_addr are
* initialized before calling EraseRoutine.
*
* After the initialization, EraseRoutine is called to erase a data block
* of 64 bytes, 512 bytes, 16 Kbytes or 32 bytes depending on the value in
* the control registers. FLASH_addr is any address within the block that
* will be erased. This program does not verify that the operation was
* successful.
