The external bank (under test) is configured for maximum reach - * with 11-bit columns and 4 internal banks. This routine will write to a max - * address (BA1 and BA0 = 1) and then read from an address with BA1=0 to see if - * that column is a "don't care". If BA1 does not affect write/read of data, - * then this device has only 2 internal banks. - * - * This routine is called to determine the ending address for this external - * bank of SDRAM. We write to a max address with a data value and then disable - * row address bits looking for "don't care" locations. Each "don't care" bit - * represents a dividing of the maximum density (128M) by 2. By dividing the - * maximum of 32 4M chunks in an external bank down by all the "don't care" bits - * determined during sizing, we set the proper density. - * - * WARNINGS. - * bp must be preserved because it is used for return linkage. -
