Appendix A
The following set of equations can be used to calculate a complete set of block addresses
using the information contained in Tables
To calculate the Block Base Address from the Block Number:
First it is necessary to calculate the Bank Number and the Block Number Offset. This can be
achieved using the following formulas:
If Bank_Number = 0, the Block Base Address can be directly read from Tables
(Parameter Bank Block Addresses) in the Block Number Offset row. Otherwise:
To calculate the Bank Number and the Block Number from the Block Base Address:
If the address is in the range of the Parameter Bank, the Bank Number is 0 and the Block
Number can be directly read from Tables
the row that corresponds to the address given. Otherwise, the Block Number can be
calculated using the formulas below:
For the top configuration (M58LT256JST):
For the bottom configuration (M58LT256JSB):
For both configurations the Bank Number and the Block Number Offset can be calculated
using the following formulas:
Bank_Number = (Block_Number − 3) / 16
Block_Number_Offset = Block_Number − 3 − (Bank_Number x 16)
Block_Base_Address = Bank_Base_Address + Block_Base_Address_Offset
Block_Number = ((NOT address) / 2
Block_Number = (address / 2
Bank_Number = (Block_Number − 3) / 16
Block_Number_Offset = Block_Number − 3 − (Bank_Number x 16)
